Thanks to our R&D team, this is a pathbreaking void product. This product is upgraded from a normal tamper evident tape. Originally, this is a tape, but we cut the whole tape into many individual pieces stickers. Then we give it a special design and make it work with a plastic shell, from which we can use it very easily. When one layer is pulled out, the next one will come out automatically. And every individual sticker will be with a non-adhesive handle, no sticky to hands when use. Easy to pull out, east to use. Also it keeps original void tamper evident function. What a new product ~!
