200 Pack 5x7 Corrugated Cardboard Sheets for Mailers, Flat Packaging Inserts for Shipping, Mailing, Arts and Crafts Supplies, Dividers, DIY Projects, 2mm Thickness

Smaller than I thought they were

This is hands down the best to pack prints. They are thick and sturdy and keep prints safe when shipping out to my customers. I recommend these backing boards. They are true to size and come safely packed.

Definitely helped me with my projects

I ship out trading cards, and I use these in the envelope, so the card doesn’t bend. These things are VERY stiff, and work amazingly well.

Perfect thickness for my postcard shipping needs.

I think most people mistakenly think the thicker the cardboard, the sturdier it is. However, these inserts are thin yet much sturdier than the thicker board I previously used. Ive purchased them three times now and all have been in great condition. As far as size, they measure exactly 5x7.

Durable and easy to assemble

Perfect to ship inside my envelopes with my stickers to keep them from bending.

I used these for an art craft. They were very sturdy, but required a lot of glue to get string to stick. It did the job, but was pricy for cardboard.

These are exactly what I needed to ship out paper goods without them bending in the mail. I am so glad that they came undamaged and better than I thought theyd be. Will purchase again.
