Quality Park Tyvek Envelopes, 100 Pack, Large 10 x 13 Envelopes, First Class Border, Easy-to-Open Tamper Evident Pull Strip, Rip, Puncture & Water Resistant Self Sealing Mailing Envelopes, White

• Self-Seal Closure: peel the liner off and press the flap shut - no moisture and no tape. The face takes a pen or a printed label cleanly, so addressing stays fast even on a whole batch going out at once.
• Skip The Carton: these are mailing envelopes 10x13 inches on the outside, and a 10x13 envelope takes paperwork a letter envelope cannot without the weight a cardboard carton adds to every shipment.
• Stronger Than Paper: DuPont Tyvek envelopes are spunbonded high-density polyethylene rather than kraft or manila stock, so they resist the punctures, tears and damp that split a paper envelope in a sorter.
• Flat And Slim: no side gusset at all, so contracts, photo prints and printed reports travel flat, and these 10x13 tyvek envelopes stay uniformly thin the way a carrier wants a large envelope.
• Office Supplies That Ship: send tax records and legal documents, brochures, lab results and school transcripts; these oversized white envelopes 10x13 come 100 to a box and keep a small business stocked for months.
