Questions about this item

How do you seal the diagonal-seam envelope with the remoistening seal?

Moisten the flap adhesive evenly, press firmly along the diagonal seam, and hold for a few seconds to ensure a secure bond.

Will the 92% brightness white sulphite paper yellow or degrade over time in storage?

The SFI-certified sulphite stock resists yellowing; keep the box sealed in a cool, dry place to maintain brightness.

At what point does the 20# paper weight limit how many sheets can be mailed without extra postage?

A single folded letter fits comfortably; multiple pages may push the envelope over the standard letter rate.
