Review on Pack Of 50 Luxury Kraft Bubble Mailers 4X8 Inches With Strong Adhesion And Self Seal, Waterproof Cushioned Envelopes For Small Business Shipping, Bulk #000 Yellow Bubble Packaging by Christine Dillard

I purchased the Kraft mailers, the bubble interior is 8.5" x 11". They are kind of "ugly", and have a cheap appeal. Imagine a stack of bubble mailers being vacuumed sealed, they have a crushed up appearance and are thin. Although they are not ideal they will work fine for mailing small packs around 1 pound or less. For a quality looking package purchase something else, but if you need the value then they will work fine.
