Hey online sellers and crafters! These poly mailers are absolutely perfect for shipping all your sewing projects and craft supplies. You get 50 envelopes in the pack, each measuring 10x13 inches - that's plenty for regular shipping without constantly reordering. The 2.35 mil polyethylene material is seriously durable and tear-resistant, so your delicate items actually arrive in one piece. The self-sealing adhesive strip is super convenient - no more licking envelopes or searching for tape. Just peel and press for a secure, tamper-proof seal. What's really great is they're 100% recyclable, so you can feel good about reducing waste while running your business. Perfect for fabrics, sewing patterns, craft supplies, clothing items, or anything that doesn't need bulky box protection. The lightweight design saves on shipping costs compared to cardboard boxes. The clear material makes address labels easy to read, and they're waterproof enough to handle rainy delivery days. Seriously, if you're tired of overpackaging or worrying about items getting damaged in transit, these mailers provide reliable protection without the bulk. Great for Etsy sellers, small businesses, or anyone who regularly ships flat items.
