### ⭐⭐⭐⭐⭐ You get what you pay for
*by A***R on May 18, 2023*

These are thin and cheap feeling compared to other mailers I’ve used. However, I have shipped out several of these with clothing, and haven’t had a single complaint. They are lightweight and don’t add much to shipping costs. They aren’t as nice as others, but if you’re looking to keep your overhead low, this is a good option.
