Intensive black cloths, for intense black and smooth fibres, 6 cloths

Helpful for cotton black clothes

It really enhances the color of the fabric — it’s not a dye, but it improves

If you need your black clothing to recover to black, its a great product. Value, it is a little bit pricey, but to think about how much money you have to spend on new black tshirt, this would be the choice.

I’m really happy with this product. The quality is excellent and it works exactly as described. It was easy to use right out of the box, and I noticed great results almost immediately. The design is well made and feels durable, which makes it worth the price. I also appreciate how reliable it has been—no issues so far. Overall, this product exceeded my expectations, and I would definitely recommend it to anyone considering buying it.

Works well, not for all fabrics types, no english instructions , made the cloth darker

It is what I had been looking for! 1 sheet for navy, 2-3 for black. 1 sheet of 1-2 clothes.

I bought this product because it was supposed to change color — but it doesn’t do anything. I followed the instructions exactly, tried multiple times, and there was absolutely no color change. It just stayed the same dull color the whole time. Totally misleading description. Waste of money and time. Would not recommend.

This stuff is AMAZING! I have a lot of black clothing, especially scrubs, which get washed, A LOT. You throw one of these sheets in the washer (2 for large loads) and your black clothes look new again. It doesn't stain your washer, definitely worth the money. I will buy again.
