Hi, I am sending in running shorts to FBA, and I am currently figuring out how to measure the products. Each pair of shorts is individually wrapped in a polybag from the manufacturer. Each bag is 15x15x1, which places my product in the “oversize” category, even though it is only a pair of shorts. Can I fold or change the shape of the product, or do I just need to eat the $9+ oversize item fee?
