5. When washing items in a laundry net, there may be cases where color unevenness occurs.
6. Store in a place away from high or low temperatures and direct sunlight, and out of reach of children.
7. Do not use for purposes other than the intended use.
8. In case of swallowing or contact with eyes, please consult a doctor.

Please be sure to check before purchasing.

Thank you for considering this product. To ensure that you experience its effects correctly, please make sure to review the following points before purchasing:

1. This product is not a “dye.”

LOVE BLACK is a detergent that restores black color by supplementing blue pigments and removing fuzz through enzymes during washing. Unlike dyes that turn garments pitch black in a single wash, this product gradually becomes effective through repeated use.

2.Effects may vary by individual and material.
Depending on the condition of the fabric or its material (especially synthetic fibers with low absorbency), it may take multiple washes to see results, or the effects may be less noticeable. Garments that have completely lost their color or are severely discolored due to sun exposure or chlorine bleach cannot be restored to their original black.

Please understand this product as an easy “anti-aging care for clothing” that can be done at home, and make your purchase accordingly.

LOVE BLACK is a special detergent created to keep black looking beautiful.

Revives faded black, while suppressing fuzz and pilling, and also addresses dullness and discoloration. It keeps black deeper and more beautifully protected.

Functions of LOVE BLACK - 01

Approach the blue pigment.

The mixture of red, blue, and yellow pigments results in "black," but since blue easily fades due to ultraviolet rays and other factors, it is the first color to disappear, causing black clothing to become reddish-black.

Therefore, by complementing the faded "blue," we restore the overall balance and approach the original black color.

FAQ

Can it be washed together with other clothes?

Black clothing and blue-toned clothing can be washed together. Other clothing items cannot be washed together with them.

What happens when you wash white clothes?

When washing white clothes, they may turn blue. Please do not wash them together with anything other than black or blue items.

Can the printed T-shirt be washed?

Yes, it’s fine. Since the print is on a material that does not get dyed, there is no problem.

What will the embroidery pattern look like?

The embroidery will be colored and turn blue.

Whether it gets dyed or not depends on the material itself. Embroidery uses cotton thread, so it is cotton. Cotton absorbs water and color, so it gets dyed.

Items like printed T-shirts that do not have water absorbency do not absorb water or color, so they are not dyed.

Can I use fabric softener?

Yes, it's okay to use fabric softener.

Which washing course?

Either the normal course or the gentle course is fine for washing.

Why does black come back to life?

1. To complement the quickly fading blue color.
2. To remove fuzziness.

These two functions revive faded black.

Does soaking it make it darker?

No. It will not be effective with soaking, so please wash it using the regular laundry mode.

Will the color transfer onto the washing machine?

Some color may transfer during washing, but most of it is removed during the subsequent rinsing stage.

If you are concerned, please either rinse once with an empty drum or wash using the drum cleaning mode.

Do the ingredients in detergents place a burden on the environment?

You can use it safely in the same way as general detergents for delicate clothing. This product is formulated with ingredients that comply with Japan’s Household Goods Quality Labeling Act and wastewater standards, and it can be treated as normal laundry wastewater without any issues. In addition to carefully selecting ingredients that reduce environmental impact, we develop our products based on the belief that “extending the lifespan of clothing and reducing waste” is the greatest consideration for the global environment.

Consideration for the environment and sustainability

We believe that “wearing the clothes you already own for as long as possible without throwing them away” is the most effective environmental measure.

Currently, the mass disposal of clothing in the apparel industry is a serious environmental issue. There is no end to garments being discarded simply because the “color has faded,” even though the fabric itself is not damaged.

FAQ

Can I wash other garments together with LOVE BLACK?

Only black garments and blue-toned garments can be washed together. Other items cannot be washed at the same time.

What happens if I wash white garments?

White garments will turn blue. Please do not wash anything other than black or blue-toned items together with LOVE BLACK.

Can I wash printed T-shirts?

Yes — printed T-shirts are fine. The printed areas are made of non-absorbent material, so they will not be tinted.

Whether a material gets tinted or not depends on the material itself. Embroidery thread is cotton, and cotton absorbs both water and color — so it will be tinted.

Will cotton thread embroidery be tinted?

Yes — embroidery will take on a blue tint.

Whether a material gets tinted or not depends on the material itself. Embroidery thread is cotton, and cotton absorbs both water and color — so it will be tinted.

Non-absorbent materials like printed T-shirt designs do not absorb water or color, and therefore will not be tinted.

Can I use it on navy garments?

Yes — absolutely. In fact, LOVE BLACK works exceptionally well on navy and blue clothing.

This detergent revives black by replenishing the blue pigment that fades the fastest during washing. As a result, when used on navy or deep blue garments, the lost blue tones are restored, bringing the vibrancy of the color back to life.

Can I use fabric softener?

Yes, it's okay to use fabric softener.

Which wash cycle should I use?

You can use either the standard cycle or the delicate (gentle) cycle — both work well with LOVE BLACK.

Why does the black color come back?

LOVE BLACK revives faded black through two key functions:

  1. Replenishing blue pigment — the color that fades the fastest.
  2. Removing surface fuzz from the fabric.

Together, these two actions bring faded black back to life.

Does soaking make clothes blacker?

No. LOVE BLACK does not work through soaking — please use your washing machine's standard wash cycle.

Will it stain the washing machine?

Some color residue may adhere to the drum during washing, but it is mostly removed during the rinse cycle that follows.

If you're concerned, simply run an empty rinse cycle, or use your machine's tub-cleaning mode.

Do the detergent ingredients have any environmental impact?

Yes — LOVE BLACK is safe to use, just like any standard detergent for delicate garments.

Our formula is composed of ingredients that comply with Japan's Household Goods Quality Labeling Act and wastewater discharge standards, and can be safely disposed of as ordinary laundry wastewater.

Beyond carefully selecting ingredients with reduced environmental impact, we develop our products with the belief that extending the life of clothing and reducing disposal is the greatest contribution we can make to the planet.

On Environmental Responsibility & Sustainability

We believe the most effective environmental action is wearing the clothes you already own, for as long as possible.

Today, the mass disposal of clothing is a serious environmental issue across the apparel industry. Countless garments are discarded simply because "the color has faded" — even when the fabric itself remains intact.

LOVE BLACK is designed to revive faded blacks, so you can enjoy your favorite pieces for as long as possible.

Of course, our detergent formula meets Japan's domestic wastewater safety standards. But beyond that, we believe the greatest environmental contribution we can make is to propose a lifestyle of cherishing and continuing to wear a single garment — and that, more than anything, is what LOVE BLACK stands for.

Please read before purchasing

Thank you for considering our product. To ensure you experience the results as intended, please review the following points before purchasing.

1. This is not a "dye"
LOVE BLACK is a detergent that revives the depth of black through laundering — by replenishing blue pigment and removing surface fuzz with enzymes. Unlike a dye, which restores deep black in a single application, LOVE BLACK delivers its effect gradually through repeated washes.

2. Results vary by individual and by fabric
Depending on the condition of the fabric and its material (particularly low-absorbency synthetic fibers), multiple washes may be required before results become visible, or the effect may be difficult to perceive. Garments that have completely lost their color, or those severely discolored by sun exposure or chlorine bleach, cannot be restored to a like-new black.

Please purchase with the understanding that LOVE BLACK is an anti-aging care for your garments — easily performed in your home washing machine.

And the aspect I am most particular about is the sense of size.
