Please understand that this is handmade, so there may be some uneven stitching. Thank you for your purchase! The inside of the pouch uses fleece that sugar gliders love(^^) There's cotton in the bottom, so it's fluffy(≧∇≦)b It's 14cm wide, 13cm high, and 7.5cm deep. Two sugar gliders can fit in it٩(ˊᗜˋ*)و It can be attached to the ceiling and sides of both acrylic and wire cages( ￣▽￣)ゞ Please wash by hand!! If you wash it in the washing machine, please put it in a laundry net!! My sugar gliders are using it and love it(*´罒`*)
