AVIDITI Small Shipping Boxes 18"L x 12"W x 2"H, 50-Pack | Cardboard Box Crush-Proof Carton for Mailing, Storing, Package, Gifts, Crafts, Business or Home, White 18x12x2 18122

I use these for my online shop. Love that the thickness can be adjusted

Great quality!

I used these boxes to send out 50 of my 2020 cosplay calendars. They were very easy to put together and sturdy. I definitely felt like my calendars were safe to send in these, and my customers who posted photos of their purchases proved to me that the boxes were strong enough to protect their contents.

This would be a good item if not for the perforations. When you fold the box along one perforation and try to assemble it the sides bend out along the next perforation line. This keeps it from having a rigid and sturdy shape.

These were $60 three weeks ago. They are now $90. People notice and it’s ridiculous. As for the boxes themselves they are great for shipping paper and my calendars but they have raised the prices so much in the past month. Really disappointing as a loyal customer who has bought hundreds of them.

This is by far the best deal i've seen online. I sell artwork of mainly prints and paintings. I've never had a complaint from any of my clients. Yes, it requires alot of tape and assembly, but it's still worth it. Buy it!

Great boxes for shipping my custom signs. The multi depth makes it easy to customize to fit a variety of what I ship.

They are definitely thin, much thinner than I receive from other stores. These mailers look like trash right from the beginning. They came all bent, with smashed corners, and dusty. When you assemble them, the edges are never that square and sharp. Even if you use a square corner to bend, it still does not look great. I don't know how these mailers look so perfect in the picture. Most likely it is just a fake image. Will be looking for a different supplier.
