WESTERN STATES #10 Window Envelope White Sulphite Black Wesco Tint 500ct

SKU CH-CY84-BSXX3

#10 window envelopes hold standard letters with a black security tint and 92 % brightness vellum finish, 500 per box

  • Professional appearance with 92% brightness white sulphite paper
  • Secure contents with black Wesco inside tint blocking visibility
  • Reliable mailing using diagonal seam construction for strength
  • Convenient addressing through C-style poly window showing recipient
  • Ready supply of 500 envelopes per box for high volume

Standard #10 Business Envelopes

These #10 window envelopes measure 4-1/8 by 9-1/2 inches and are designed for everyday business mailing. The white sulphite stock carries SFI certification and a 92% brightness level with a vellum finish. A black Wesco inside tint adds opacity to protect document privacy. Each box contains 500 envelopes suited for high-volume office use.

Moisture-Activated Seal and Window Design

The remoistening seal requires only water to close securely, while the flap-down configuration keeps the seal protected until use. A C-style poly window measures 1-1/8 by 4-1/2 inches to display recipient addresses clearly. Diagonal seam construction reinforces the envelope edges during handling and transit.

Unlabeled Soft Box Packaging

The envelopes ship in an unbranded soft box that simplifies storage on shelves or in supply cabinets. This neutral packaging allows businesses to reorganise stock without visible supplier markings. The bulk 500-count quantity reduces reorder frequency for mailrooms processing regular outgoing correspondence.

Questions about this item

How do I load the envelopes so the 1-1/8" x 4-1/2" window aligns with the address block?

Insert the stack with the window facing up and the flap down; the diagonal seams run from the lower corners to the centre, so the window sits automatically in the standard #10 address window position.

Will the remoistening seal lose its tack over time?

The gummed flap is designed for single use; once moistened and sealed it cannot be reused, so keep the box sealed until you are ready to mail.

Does the Black Wesco tint fully block the contents from view under bright light?

The interior tint is formulated to obscure printed text at normal office lighting; it is not rated as a security envelope for high-intensity inspection.
