Quality Park Redi-Seal Catalog Envelopes (Model QUA43762) are 10 x 13 inch mailing envelopes made from heavyweight 28 lb brown kraft paper, sold in a box of 250.

These envelopes feature Quality Park's Redi-Seal closure system — a pressure-activated latex adhesive applied to two surfaces that bonds securely when pressed together. No moisture or paper strip removal is required, making them ideal for high-volume mailing tasks. The center seam construction adds extra strength when the envelopes are filled with heavier contents.

The heavyweight 28 lb kraft paper is opaque to protect private contents and durable enough for demanding office and shipping tasks. The large 10 x 13 inch format accommodates catalogs, documents, and flat-packed items up to standard letter size without folding.
