■ Hayashi Hat Co., Ltd. ■ Children's Swim Cap ■ Size...M ■ Color...Black ■ Material...80% Nylon, 20% Polyurethane ■ Made in Japan This item was passed down from a family member. It seems it was used at a kindergarten. When I tried it on my first-grade son (who has a large head), it was too small and tight, so I think it's a size for kindergarteners or nursery school children. The circumference of the opening, measured without stretching the elastic, was about 45cm. There are no major stains. No pets, no smokers. Fabric softener has been used.
