This is a free-size New Era cap, also made with stretchy material. The top is also a soft material, so it will be shipped in a "Yu-Packet Plus" box, and may be slightly flattened. Please understand that this is a used item that has small spots of dirt on the inside and has been stored at home. We kindly ask for your purchase. In addition, for packaging, we will basically use reused materials from an eco-friendly perspective. TBS Era Hat, Taiyo Whales, DeNA, Shonan Searex
