120 pcs Tamper Evident Label Sticker with Bar Code Total Transfer Security Warranty Void Seals/Stickers for Reusable Package with Serial Number(1 x 3.4Inches,Yellow)

So, they are really too small for what I needed, but I ran out of time and had no choice. I needed to secure documents in plastc boxes. The labels barely made it from the tops' handles to the bottom boxes. So, I also used packing tape to hold the tops on to prevent accidental dislodgement of the tops which would have broken the seals. On 1 of the boxes, my hand slipped and I ended up putting a label in the wrong spot, so I tried to remove it, which was a bad idea, because that left not only a yellow tape which can come off, but also it left sticky residue behind, which I could rub off the box (so much for security), but not off my fingers! I had to use acetone to remove it from my thumb. However, if you're using it on paper or cardboard, you'll never get it off! Which is what it's designed for!

Not the greatest but they work ,surfaces had to be really clean so you can use them
