12.5 x 4 x 20 - 12G Gusseted Reinforced Mailer 250/Case

These envelopes are made by sandwiching laminated fiberglass strands between kraft paper layers. This design gives them extra tensile strength and excellent protection against grease, water, and oil. The laminated fiberglass reinforcements prevent the bags from tearing, puncturing, and abrasion. As they are unpadded, these reinforced bags are cost - effective for mailing. They are perfect for securely sending items that don't need cushioning.

To use these mailers, simply place your item inside and seal it up. They're great for sending things like documents or small, non - fragile items. When handling, try not to put too much pressure on sharp objects inside to avoid tearing. There's no special maintenance needed, just store them in a dry place to keep them in good condition. Since they're not padded, don't use them for items that could break easily.
