This is a popcorn knit cap from UNIQLO's collaboration with MARNI. "Popcorn knit" refers to a knitting technique where parts of the knit are puffed out in a rounded, three-dimensional way, creating a bumpy surface that resembles popped popcorn. This knit cap features a combination of yellow and beige with a dark brown line. It is ONE SIZE, with a length of 21 cm and a head circumference of 48 cm, but it is stretchy, so anyone can wear it. Please consider it.
