Plus a little update *by M***N on November 2, 2023* This 2nd purchase, the adhesive tab is not as thick as the first set, a bit of a difference but not bad still like them a lot. The material is also not as shiny as the first time I purchased. A bit dull looking but still I like them a lot. I would want a different colour but the price is amazing for the plain black...........Still a BUY BUY BUY for me. I had purchased these polymailers and only a few left from the first order. They are great! They are not thick but very strong. The colors is true black and the adhesive is amazing. Out of the 100 pack not 1 was a problem. When you peel off the adhesive that's it, no turning back. Never had an issue with any holes or tearing. Great product. The second order which I have, it came packaged not so nicely but if the quality is the same there is no complaints. I will update, on the second pack. I've ready counted the second pack, yes I'm that person. I would like other colors but because I trust the quality of the black and the price was amazing.
