I like to shop for shoes online, and I like to return them too if I’m not satisfied with the product. :) I bought 3 pairs of shoes, so all three where shipped in a huge box. I wanted to return a pair but I didn’t have a shipping box for it. These mailers were perfect with the help of a few inches of tape. These mailers will make returning online purchases more convenient. I’m happy with my purchase and I will purchase again in the future when I ran out.
