Excellent Quality and Value!
I’ve been using these Metronic poly mailers for shipping large items, and they’ve exceeded my expectations. The 14.5x19 size is perfect for bulkier products like clothing, soft goods, and even small boxes. The material is durable, offering great protection during transit. I also appreciate the strong adhesive strip—it seals securely and doesn’t peel off easily. The pack of 100 is a great value for the price, and the clean, professional look adds a nice touch to my packaging. No tears, no leaks, and they hold up well even in rough handling. Highly recommend for small businesses or anyone needing reliable shipping supplies!

Great quality
Good quality. Large enough for a bigger thick sweater with no problem. They are strong and thick. The color was just as shown.

Really great quality plastic bag, very strong seal
Really great value for the money. Fits an average size shirt very well, I'd say like a men's size large dress shirt or smaller. Doesn't fit thicker things like sweaters or hoodies nicely . The plastic is very thick and very good quality. The seal holds very well.

Good buy
Great bags to use for my online clothing store. Wish they were a little thicker but seals great. Great value for money. Doesn’t have padding. Wish it came in more designs though.

Great for small businesses!
I use these daily for my small business. They are a little thinner than some polymailers I have had, and sometimes they get a hole in them just from picking up the package, but overall they are pretty good quality and it is a great price!

Durable and Perfect for Online Sellers
The Metronic Poly Mailers are a game changer for my online business! These 14.5x19 large shipping bags are the perfect size for clothing and other items I sell, and their durability is outstanding. The material is strong and tear-resistant, providing excellent protection for my shipments. I never have to worry about items arriving damaged or the bags ripping during transit. The adhesive strip seals securely every time, giving me peace of mind that my packages will stay closed until they reach my customers. These mailers are lightweight yet sturdy, which helps save on shipping costs while still looking professional. If you’re an online seller looking for reliable, high-quality shipping bags, I can’t recommend the Metronic Poly Mailers enough!
