This is a HOEI Oyasumi Cover C-type. It's for the Heartful House M and Tenori 21 cages. I used it for two winter seasons. I'm selling it because I bought a new cage. There is a stain next to the HOEI letters (see photo 3). There are no tears that affect its use. This is a used item, so please refrain from purchasing if you are concerned about minor details.
