Blue Summit Supplies 13 x 18 White Security Catalog Envelopes give offices, print shops, and mailrooms a secure, professional way to mail oversized documents and prints without folding. A printed security tint inside blocks see-through, so large reports and confidential paperwork stay private in the mail. Each envelope closes with a self-seal flap: peel the strip, press it down, and it seals in seconds with no licking and no metal clasp to bend or snag. The jumbo 13 x 18 size holds big reports, posters, and oversized paperwork flat, so your materials arrive crisp and professional rather than folded or creased. With a clean white finish, these mailers take stick-on shipping labels neatly for a polished presentation. With 50 envelopes per pack, you keep a dependable supply on hand for jumbo mailings, and the same envelopes work well for storing and protecting large documents and prints. Because this is a large, lightweight envelope, adding a stiffener for flat items and a strip of tape for heavy contents helps everything arrive in top shape.
