How to use

Prepare the item to be mailed so it fits the C6 envelope size; letters can typically be folded twice to fit.

For bulk mailing, load envelopes into an addressing or inserting machine according to the device manufacturer’s guidelines. Store unused envelopes flat in a dry environment to prevent warping or moisture damage.

Recommendations

For reliable results when printing addresses, test your printer feed with a small number of envelopes first and adjust settings for paper thickness. Keep the envelopes in their original packaging until use and avoid exposing them to high humidity to maintain sealing performance and paper quality.
