Had been using another brand but saw these were slightly cheaper so thought I would give them a chance. VERY IMPRESSED with the quality! MUCH more durable that what I had been using and also the adhesive strip protector isn't staticky so it doesn't stick to my hand when throwing away. Will be back to buy more!

They work great for mailing small items, they came in a clutch recently since I ran out of small bubble mailers for my keychains. The adhesive seals really great and weigh barely anything. So far they seem to be decently durable. Would definitely buy again.

Quality of poly bag is really great. Peek back strip with glue is very strong once secured when closing up the bag. I love the availability of sizing.

Like other people mentioned these are very thin. It works for our needs at the current price level it's worth. I ordered a different brand in the past that is much much sturdier but prices went way up so we decide to try these. I would recommend ordering an small qty to try first. If the prices for these go up then I will just go back to the other sturdier options in the market. They glue works very good but sharp or heavy objects may cut or make holes into the mailer envelope. We will continue to order these because they do the job and fulfill our needs for now. So I do recommend.
