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!
