【Sold Individually: 4 Sheets】 Dr. Beckmann Black & Fiber Refresh Black Revival Sheets ※ Due to the limited price, no discounts are available. I will delete comments asking for price negotiations. ※ Please refer to the image on the second photo for usage instructions. Previously, I included a copy of the box, but to be eco-friendly, I have reduced this and now provide the instructions in the image, which allows me to offer a discounted price. Shipping will be via regular mail. The sheets will be folded and placed in a waterproof bag with a zipper, which may cause creases, but this will not affect the product's effectiveness. Please understand. If you prefer anonymous shipping, it is available for an additional 100 yen. Please let me know in the comment section before purchasing. 【How to Use】 Place black clothing in the washing machine, along with your usual detergent and 1-3 of these sheets (the more sheets you use, the darker the color and the smoother the fabric will be). After washing, discard the sheets in the trash. ※ The box with usage instructions is not included, so please be sure to check the "How to Use" and "Precautions" in the second photo. No comment needed, instant purchase is OK. Also selling 2 sheets (470 yen), 3 sheets (570 yen), and 6 sheets (1000 yen, Mercari shipping).
