Rilakkuma Super Mochimochi Cushion (S) This is a Rilakkuma Store exclusive item. 2017 Please refrain from purchasing if you are concerned, as it has been stored for a long time. I have kept it in a bag, so it appears to be free of noticeable stains. It's a cushion with a soft, mochi-like texture. After taking measures to protect it from water damage, I will compress it slightly and ship it via anonymous delivery.
