WESTERN STATES #10 Poly Window Envelope 4.125 x 9.5 24# White Diagonal Seam Black Wesco Tint Box 500

SKU CH-3EXH-WXKX8

White #10 envelopes with a poly window and black Wesco tint for privacy, 500 per box

  • #10 size fits standard business correspondence
  • 92% brightness white paper for clear prints
  • Black Wesco tint blocks document visibility
  • Poly window shows address without extra labels
  • 500 envelopes per box for high-volume mailing

Standard #10 Business Envelope

These #10 envelopes measure 4.125 x 9.5 inches and use 24 lb white sulphite paper with a vellum finish. A poly window sits 7/8 inch from the left and 5/8 inch from the bottom, sized 1-1/8 x 4-1/2 inches for standard address blocks. The diagonal seam construction and remoistening seal suit high-volume mailing equipment. Black Wesco tint on the interior obscures contents for privacy.

Suited for Bulk Invoice Mailing

Offices sending statements, invoices or cheques in batches of 500 will value the SFI-certified stock and 92% brightness for clean print contrast. The tinted interior prevents read-through on sensitive documents. Buyers needing peel-and-seal closure or a larger window format should look at other lines, as this box provides only remoistening glue and the fixed B-style window position.

24 lb Sulphite Paper Weight

The 24 lb basis weight defines the sheet stiffness and feed reliability in laser printers and inserters. It balances opacity against postage cost for multi-page inserts. If your inserting machine specifies a different basis weight or your postal rate calculation requires a lighter sheet, this specification determines whether the box is compatible.
