Mountain Clay Mailers 6" x 9"

These are hands-down my favorite poly mailers to use for my customers. I’ve tried a lot of options over the years, but these stand out for a few big reasons. First off, I really appreciate that they’re biodegradable. It’s a nice touch knowing I’m shipping my products in packaging that’s a little easier on the planet.

But what really sold me is the quality. These aren’t those cheap, thin plastic mailers that feel like they’ll tear if you look at them wrong. These are thick, heavy-duty, and clearly built to hold up during shipping. I’ve packed them full and they’ve held up every time. I feel confident that whatever I’m shipping is protected, even if it gets tossed around a bit in transit.

Another small but important detail—when you peel off the adhesive strip, the leftover plastic doesn’t get annoyingly staticky and cling to everything. It sounds like a little thing, but if you’re packing lots of orders, it makes a big difference in how fast and smooth your workflow feels.

As for looks, I love the designs. The mountain design is my personal favorite—it fits perfectly with my brand and the outdoor gear I sell. If I had one tiny note, I’d say I wish the red tone in the design leaned a little more toward auburn or deep red instead of pink, but that’s just personal preference. It still looks great and my customers always comment on the cool packaging.

Overall, these mailers are awesome. They’re strong, well-designed, eco-conscious, and thoughtfully made. They check all the boxes for what I look for in packaging. I’ll definitely keep using them for my business and recommending them to others.

Love the vibrant prints. Great quality for shipping and the adhesive is awesome.

For being biodegradable, these are a fantastic price! I use these for shipping t-shirts all the way up to 2xl and, if rolled well, it fits no problem. The print quality is perfect, and I like that the material "stretches" more than tears; I half-expected them to be too hard or crinkly but they are very flexible. The adhesive is very sticky, so you have to commit when closing it up. Def recommend!
