Kids' swim cap with a brim. It also has neck protection! The chin strap is a tie-up type. Free size, for ages 1-9, and the head circumference can be adjusted at the back. Used a few times. Please note that the shipping method (Rakuraku Mercari Bin or Yu-Yu Mercari Bin) may be changed without notice. If you have a preference, please let me know in advance ( >_< ) To reduce the thickness for shipping, it will be compressed, and there may be creases. Thank you for your understanding. I inspect carefully, but there may be oversights. Please understand that this is a used item.
