I'm a self fulfilling Amazon seller and like to have my items pre-packaged and ready to ship. These allow me to quickly attach the shipping invoice to a specific pkg and have it out the door to the post office. They are easy to apply and you can put the envelopes on ahead on time leaving the closure strip in place until you are completing the order, then remove strip and seal- easy peasy. This has made life so much easier!

Works for what it is. Only suggesting is that the back (white part) be a bit stiffer so that inserting packing slip would be easier.

These packing slips don't get all stuck together when you take the tape off to stick them to a box. They're thicker and better than other ones that I've purchased. I highly recommend these and we'll buy them again.

Once you take the peel off and stick these on they are not coming off. Good quality but I do wish they were a little larger.

Overall, these are great for the price and does stick... however, I find when I quickly tear the back off to stick it on my box, there is usually leftover paper pieces from the strip so I have to try to pick the tiny leftover pieces before I stick it on my box. If I don't take all the pieces off, it doesn't stick very well to the box. It seems the trick is to go super slow when removing the back.
