You can purchase without a comment (^^) I've put together two cute ones in a set! These are 1200 yen each. *These are autumn/winter futons. They can be attached to Usa-Dan M (body size 16x23) and won't slip because they have rubber bands. You can change the pattern and color (I have a confirmation listing where I've put the fabric patterns, so you can change them here). If you can't find it, please comment. I'll create a dedicated listing and put the fabric patterns in the second photo. 100 yen off for a set of 2 150 yen off for a set of 3 200 yen off for a set of 4 Up to 4 futons can be shipped together. *Size (body 16x23) 18x25 (hidden part entrance 26x18) The entrance has a gusset and is made wide, so I think you can fit up to two animals. *Ho-tto Kibun (body size 14.7x21.0) *Hotto Usa-Poka Heater M (body size 14.7x19.8) *Hotto 2WAY Heater M (body size 14.6x20.8) *Marukan MLP-25 Hedgehog Reversible Heater (body size 16x23) These sizes are also available, so please comment. It will be 1200 yen. Usa-Dan is not included. The Usa-Dan in the photo is a new one. *If it's been chewed and has holes, there's a risk of getting claws caught, so please stop using it. *The fabric pattern will vary.
