Amazing packers!
These are super nice! I love that they re compostable....I reuse all my amazon packages to ship stuff out but sometimes I need sleeves and these are great. Well worth the $$$. They stretch well, thick, stick well, and have a great minimal look to them! Shipping labels also stick well to them!

Buy in small amounts if you don’t really sell much
I bought these and left them aside for whenever I sold a jersey. After 6 months or so (possibly less) they become weak, like a leaf. They’re great and need insane amount of force to tear the packaging when they’re fresh, so make sure you only buy what you need within three months.

Weird film or white powder?
I’ve ordered these before, but in my last purchase the mailers had a weird film that felt like a fine powder. I have to wipe it off before shipment for the shipping label to stick. Otherwise, I’ve never had issues with the adhesive not working or failing during shipment or the mailer breaking.

Great Eco Friendly Option
These poly mailers are great if you are looking for an eco friendly option. I have a small business and wanted eco friendly poly mailers, so these have been working out great. I have had one customer show me that the bag ripped a little on the bottom, but their product was not damaged so everything worked out in the end. Despite that happening with one customer, I still love these mailers because I can also fit quite a bit in it.

Great!
A nice feel, decent price until economies of scale can lower that price (better than any other biodegradeable in this size still I think), A strong adhesion on the flap, not brittle but stretchy. I print labels onto normal printer paper and then attach them with plant based packing tape (the clear stuff) and the adhesion feels fine to me, sometimes its powdery but the tape doesnt seem to want to come off from my experience. Some people were saying they had problems with adhesion with labels I didnt with my attachment method. Your results may vary.

After 6 months it may rip easily
I had this for over 6 months & the bags start to rip/tear easily. I'm assuming it start biodegrade. I still use it & use tape to hold it closed. It's fine to ship clothing but anything that is fragile to ship, this alone will not do the job.
