Questions about this item

Will the 6 x 9.5 inch size fit a folded letter without creasing the 24 lb paper?

The open side measures 6 by 9.5 inches, so a tri-folded letter slides in flat and the 24 lb sulphite stock resists creasing during insertion.

How can I verify the 92% brightness and SFI certification on the white envelopes?

The vellum finish shows a crisp 92% bright white surface, and the box label carries the SFI certified mark for responsible fibre sourcing.

Does the box of 500 include any moisture-activated seal strips or must I buy them separately?

Each envelope has a remoistening seal flap built in, so the 500-count box needs no extra sealing supplies.
