This is a single-size flat sheet. Size: 150 x 260 cm, also fits long sizes. Please note: This is not a fitted sheet. I bought it because I wanted 100% cotton, but I haven't had a chance to use it, so I'm selling it. I hope someone who needs it will buy it. See photos 3-4 for size and material. Purchased 1 year ago. No pets, no smokers. No comments needed, instant purchase OK. Depending on the packaging, I may change the shipping method between Rakuraku Mercari and Yu-Yu Mercari.
