Check flap style and paper weight
Verify that a square flap with a remoistening seal matches your sealing preference. Confirm that 28 pound vellum-finish sulphite meets the thickness and texture requirements for your printer or handwriting needs. Ensure the side-seam construction fits any automated inserting equipment you use.
Vellum finish handles cleanly
The smooth vellum surface resists smudging during handling and feeding. At 92 percent brightness the white stock presents a crisp background for printed or handwritten addresses. Lightweight construction keeps postage costs predictable for standard mail classes.
