Qilery100 Pcs Shipping Boxes Cardboard Gift Corrugated Cardboard Boxes Mailer Packaging for Mailing Small Business Present (5.91 x 3.94 x 1.57 Inches)

This size is perfect, and easy to put together. Great quality and these were the least expensive boxes I could find in this size.

Excellent quality materials

perfect size for me to ship small items and strong.

Sturdy box. Good for shipping small items.

Most boxes were intact, however, some showed up looking like they were cut down the center by a box cutter..the ones cut were hidden in the middle of the 100 piece stack.

Small mailer box that I use for jewelry sales. Perfect size & I use 1 bubble sheet. Perfect 4 my small business. Easy storage as it's flat & easy to fold up.

Internal dimensions are 5.5x4x1.5. cardboard is very thin. Usps small flat rate box for comparison. The usps box cardboard is sturdier. They will work but ill try a different brand next time.

These boxes are not crush-proof, but extra packing tape will help to reinforce the edges. What I like best is that they are really light weight, so it is easy to keep my packages under the 4 oz. threshold, which saves on shipping costs. I did have one box get practically flattened in transit, but it was clear that something very heavy must have been dropped on it, so all the padding in the world probably wouldn't have mattered. Cost of doing business and the savings on all the other packages that don't get crushed, more than makes up for it.
