This is an authentic Detroit Tigers cap. The size is 7 and 3/8, 58.7cm. The brim is slightly curved. Not recommended for those who want to curve it from scratch. The item itself is in good condition, having been worn less than 3 times, but it is still a used item. The sticker has been removed to prevent discoloration. Please refrain from purchasing if you are sensitive to the condition, as it has been stored by a private individual.
