Metronic Poly Mailers 24x24 100 Pack, Extra Large Self Seal Shipping Bags

As an eBay seller specializing in clothing, reliable shipping supplies are a non-negotiable part of my daily business. I have purchased Metronic poly mailers before, and they never fail to impress me with their quality. Picking up this 10x13 1,000-pack was easily one of the best bulk buys I have made for my store. These mailers are exceptionally durable and have just the right amount of stretch to fit bulkier apparel items without tearing or splitting at the seams. The adhesive peel-and-stick strip has a very strong seal, so I never have to worry about packages coming open during transit. The 10x13 size is the sweet spot for t-shirts, jeans, and light sweaters. On top of the already fantastic quality, it felt like they even threw in an extra 200 bags in this bulk order, which is a massive bonus for a small business owner watching margins. Overall, these bags are consistent, super reliable, and worth every penny. I love these mailers and cannot recommend them enough to fellow resellers or anyone needing quality packaging!

They do the job! The color is not very bright, the are closer to grey They are light weight but durable They are worth the money.

These are a practical size for shipping things like shirts, soft goods, small accessories, and other items that don’t need the protection of a cardboard box. The 10x13 size gives you enough room to work with without adding a bunch of unnecessary package size, and the self-seal design is much quicker than having to tape every mailer closed. I also like that they’re plain white with a clean outside surface, which works well for shipping labels and doesn’t make small-business orders look overly busy. With 1,000 in the case, they make a lot more sense if you’re shipping regularly rather than buying mailers in small packs. These obviously aren’t meant to protect rigid or fragile products from impacts, but for clothing and other lightweight items where you mainly need a clean outer shipping layer, this is exactly the type of packaging I’d use.

The Verdict: Professional Surface Protection That Stays Clean We’ve been using these poly mailers for our bulk shipments for quite some time, and they provide an excellent layer of security. While they aren't meant to prevent internal damage from heavy impacts or crushing, they are perfect for keeping boxes pristine, scuff-free, and bone-dry. Our recipients consistently mention how professional and well-packaged their items look upon arrival. Fit Guide: Excellent Coverage for Standard Boxes The sizing is incredibly convenient for a variety of shipping needs. A single mailer provides a full, snug fit for boxes around these dimensions.: 12 1/4 (L) x 12 (W) x 6 (H) =priority mail flat rate large box 14 1/8 (L) x 12 (w) x 3 1/2 (H) = priority mail side loading medium box If you’re using a bigger box, you may need to overlap mailers to make sure it’s covered Key Highlights: • Reliable Seal: The peel-and-stick adhesive strip is quick and convenient to use. • Extra Peace of Mind: While the adhesive holds well, we still add a bit of extra tape for added protection to ensure the flap stays perfectly secure during transit. • Weatherproof Barrier: Provides a reliable shield against rain, snow, and moisture from the warehouse to the doorstep. • Tough Material: The plastic is thick enough to prevent dirt, scuffs, and minor surface tears to the inner box. • Versatile: For oversized shipments, the material is sturdy enough that you can easily overlap two mailers for full coverage. These have become a staple in our shipping routine. If you need to ensure your items stay clean and dry regardless of the weather, these are a solid investment.

So there were a lot of mixed reviews for this product leaving me hesitant to buy these. My boyfriend needed them for a studio upstairs so we just took the risk and bought them. They have been up for a month now and none of them have lifted or fallen what so ever and we used the adhesives provided to us. We followed the instructions and wiped down the walls before placing the panels. As far as the thickness goes some of the panels were slightly skinnier then others, but that is expected when they are vacuum sealed. We had plenty of panels that were full thickness and we didn’t even need all of the panels we bought. It definitely helps with the echo, and for the reviews claiming it isn’t sound proof, that is not the goal of these panels. These panels are used to absorb the sound waves to prevent echos though it may slightly help with sound proofing. Overall for the price I would go for this product. Plus they are cheap enough that if they were to fall, you can get some replacements and you may even have some left over.

The color matched perfectly with what I saw online. The durability was about average. I only had one snag but I could see that being a problem depending on what you're shipping; my items were all flat and uniform. I didn't like that you could see through the poly mailer. You could see bold writing through the mailer so many times I added a blank sheet of paper to prevent that. This may not matter to you and in that case, these will suffice.

Excellent quality and durable material; it has plenty of space.

I have used these mailers in my boutique for years. I love all of the color options. These are the perfect size for larger orders or bulkier items especially during the fall and winter months when I am shipping alot of outerwear.

They are super thin, I don't know if they will be resistant.

Poor quality. As size is 24x24, strength should be there too.

Me encantó la calidad y el color

Buen producto, de acuerdo a la descripción. Considero que es de buena calidad respecto a su costo, y llegó muy rápido. Lo recomiendo.

Si vous êtes du genre à mettre deux sacs d'épais au cas où... Alors c'est un bon choix très grand! Mais je n'ai pas confiance en ce polymailer ci pour un seul sac d'épaisseur... Il y en a des vraiment plus épais.
