WESTERN STATES Open End Catalog Envelopes 10 x 13 24# White 92% Vellum Center Seam Flap Down Box 500

Open-end catalog envelopes 10 x 13

These open-end catalog envelopes measure 10 by 13 inches and come in a box of 500. They suit offices, schools and mailrooms that send flat documents, catalogues or reports on a regular basis. The 24 lb stock provides a sturdy feel for professional correspondence.

Vellum finish and remoistening seal

Check that your mailing process can handle a vellum surface if you plan to print addresses directly onto the envelope. The remoistening seal requires moisture to activate, so ensure a dampener or moistener is available in your workflow. Confirm that 10 by 13 inches fits your postal rate class and any automated inserting equipment you use.

Center seam construction and flap-down format

The center seam runs down the middle of the envelope, which affects how printed artwork aligns across the back panel. Flap-down orientation means the flap is on the short 10 inch side, changing how the envelope feeds through inserters or sits in trays. The 92 brightness white stock improves readability for handwritten or printed addresses.
