Single-size fitted multi-sheet, 100% polyester, from the 2024 Winter Collection. Purchased in December 2024. I realized I had the wrong size after opening it, so I couldn't use it... I stored it in a garment case for about a year. I'm listing it for sale since I won't be using it. - Product Name: Fitted Multi-Sheet Single (N Fit CW2420 MO S) 2024 Winter Collection - Material: 100% polyester (includes 5% polyurethane) - Size: Approximately 97 x 197 x 30cm (compatible mattress size) - Compatible Mattress Size: Approximately 100 x 200 x 30cm (compatible mattress size) - Suitable Mattress Size: Approximately 100 x 200 x 30cm (compatible mattress size) Thank you for looking.
