Pottery Barn Kids: Mackenzie Navy Solar System Backpack (Small) Very good used condition. Only sign of wear is on the outside buckle that is a little scratched up (see picture), not very noticeable. Small size, please see picture of size chart and dimensions. I think this is best for 1st thru 3rd grades depending on your child's size. Very durable material and washable! Padded back and straps. See picture from pottery barn for other information! Very popular backpack! Sold out online in small for 2023! Accessories such as matching lunch boxes and pencil cases still available (for now).
