This is a cushion cover, pillow cover, towel, or cloth.
Mikoto Misaka and her "sister" Misaka from "To Aru Majutsu no Index," regard you warily from one side of this huge pillow cover, and somewhat less so on the other side! The pillow cover measures 150cm by 55cm, and is made of 95-percent polyester and 5-percent polyurethane for two-way stretch; it's the perfect size for the included pillow, which is stuffed with 100-percent polyester for maximum squeezability!
