Shipping Boxes 12x9x3, HERKKA 20 PACK White Corrugated Cardboard Mailer White Gift Box, Medium Mailing Boxes for Small Business Packaging Supplies

Decent boxes but very lightweight and thin. Doesn’t look like they’ll stand up too well to a USPS beating.

We used these to ship our products to customers. They were sturdy and easy to fold.

I have a small business and I got Damaged packages, I would only recommend if your mailing something like clothing it would work fine

These are so thin, I don't think I can ship with them. I'm going to look into getting a refund because of the poor quality of these.

I think these are fine for mailing out a small book here and there or lightweight items but they're not what I would call durable. They have definitely been used because of their shape here in my antiques business, but I don't think I would trust anything breakable as they're a bit on the thin side. I guess because of the depth versus the width it makes them more pliable.

These are easy to fold and hold up well.

Nice boxes. But would need extra packing if you are shipping anything fragile.

I love these foldable boxes because they take up so little room. You can snap them together almost just as quickly as taping any other box together and they are nice and sturdy. I do tape down the one side just to make sure they don't pop open in transit. But these are wonderful. Very happy with them!
