This is a collaboration cap between NEW ERA and Snoopy. It's a 59FIFTY model in kids' size, and the size is 6 5/8 (53cm). The black color with the Snoopy embroidery is cute, and it's a design that's easy to wear for both boys and girls. Used a few times. Please refrain from purchasing if you are sensitive to used items, as it has been stored at home. Instant purchase is OK.
