Kontex MOKU TUBE Moku Tube Soft Type Pillowcase Neck Warmer Belly Band Cushion Cover Kontex Made in Japan Cotton Pile Imabari Towel I bought this for my Jibun Makura (custom pillow), but it didn't fit because the pillow was too big and bent. It's made of soft towel fabric and is very stretchy, but please note that it won't fit pillows that are too large.
