These corrugated mailers have a rigid exterior with fluted inner construction to cushion and protect your products.

Corrugated envelope inserts protect photographs, postcards and other paper items by stiffening the envelopes to keep them from being bent in the mail. These also provide a layer of protection for your items. One insert per envelope is recommended, because these are made to fit snugly, to help prevent tearing while being shipped. Self-Seal ends feature a cohesive seal so envelopes only stick to themselves. Just fold and press!

The flexible fluted corrugated construction is designed for easy loading.
