Daiso Scrub Cloth 34 sheets in a pack. I believe I used 2 or 3, but I'm not certain. Please allow for some margin of error. Also, there is no instruction manual. If you're okay with shipping them detached from the roll, the shipping cost will be slightly cheaper, so I can lower the price to 770 yen. (In that case, I plan to ship via Yuu Yuu Mercari within 2-3 days) Please consult with me in the comments.
