Questions about this item

How do I seal the remoistening flap without it sticking too early?

Apply moisture only along the gummed edge of the 9.5 x 12.5 in envelope and press firmly; avoid wetting the vellum-finish body or the center seam area, which can cause premature adhesion before the catalog is inserted.

When will the box of 500 envelopes need to be replaced?

Replace the carton once the 500-count supply is exhausted; the 28 lb White Kraft stock and SFI-certified fibers do not degrade under normal office storage, so no scheduled material replacement is required.

What is the maximum insert thickness before the center seam stresses?

The 28 lb White Kraft construction with center seam handles typical catalog stacks; exceeding a 12.5 in fill depth or forcing bulky items can strain the seam and vellum finish, so keep contents within the 9.5 x 12.5 in envelope profile.
