How to use

Unfold the mail bag and place the documents or flat items inside so they lie flat against the padded interior. Fold the top flap and engage the closure to secure contents; if the closure is adhesive, remove protective strip and press firmly, or use tape where additional security is required. Address and affix postage on the exterior surface, keeping labels flat and avoiding overfilling beyond the 4 cm depth to ensure reliable closure and postal compatibility.

Recommendations

For best results, use these padded B4 mail bags for flat items that benefit from light cushioning and a tidy exterior. Avoid inserting bulky or sharp objects that could compromise the padding. When sending important documents, combine with an internal stiffener if rigidity is required, and verify postal size and weight limits before dispatch.
