WESTERN STATES #10 Business Envelopes 92% Brightness Box of 500

Standard Business Size

These #10 envelopes measure 4-1/8 by 9-1/2 inches and fit standard letter sheets folded in thirds. The box contains 500 pieces suited to daily mail runs for offices, schools or home workspaces. White sulphite stock with 92% brightness gives a clean, professional look for correspondence and invoices.

Pressure Seal and Vellum Finish

A pressure-sensitive adhesive on the 2-inch square flap removes the need for moistening or separate glue sticks. The vellum finish adds a subtle texture that resists smudging during handwriting or laser printing. Two side seams under construction keeps the closure secure through automated inserting equipment.

SFI Certified Sulphite Stock

Paper carries SFI certification, confirming responsible fibre sourcing for buyers with procurement policies. No window means full printable area for return addresses or marketing messages. The square flap folds flat for neat stacking in trays and trouble-free feeding through postage meters.
