Tate-yoko Stretch N-Fit Fitted Sheet Small Single-Single (FT03 Plain IV SS-S) Beige Used for about a year. Used to protect the mattress. I put a mattress pad on top of this fitted sheet, so it wasn't used directly. As shown in the photos, there are some areas that have become like pills due to friction with the mattress pad. They are like small black pills. I washed it regularly and bleached it to keep it clean, but it is not new, so I would appreciate your understanding. This is the price for one sheet. I have another one, so if you would like to purchase them together, I will sell both for 2600 yen, so please comment! Thank you.
