This is a fleece pillowcase. It's a bag type, measuring 38 x 88cm. You put the pillow inside and fold over the opening to use it. I washed it after opening, but I never used it and have been storing it at home. (I bought it to keep warm, but I ended up sleeping with the heater on, so I didn't need it.) The block check design is also cute. How about it for couples?
