* These are summer/spring futons. The front side is cotton fabric, and the inside is fluffy. You can also have the inside made of plain cotton fabric, so please let me know if you'd like that. It can be attached to Usa-Dan M (body size 16x23) and won't slip because it has elastic. * Please comment if you want a fluffy one for autumn/winter. * Sizes (body 16x23) 18x25 (hidden part, entrance 26x18) The entrance has a gusset and is made wide, so I think you can fit up to 2 animals. The pattern will be the one in the photo, but you can change the color/pattern (I have a confirmation listing, so I've put the fabric patterns there, and you can change them). If you can't find it, please comment. I will put the fabric patterns in the second photo after creating a dedicated listing. If you want two, please comment first. 2-piece set: 100 yen off 3-piece set: 150 yen off 4-piece set: 200 yen off Up to 4 futons can be shipped together. * Ham-Dan size (body 9.2x14.2) 11x17 (hidden part, entrance 20x13) This price is 1000 yen.
