I needed some good but cheap tamper stickers for doing device repair work for clients. Not that I've had much fraud but the stickers just there to keep honest people honest. The adhesive on these so far is very good and they have good visual appeal and the contrast seems fine as well. If you're looking for basic stickers for packaging, potentially access panels, possibly paper packet sealing, or other places where you want a seal that's going to show evidence of tearing or tampering if someone tries to separate it or tear through it, these should work just fine for your needs.

I tried these on several surfaces, and they work well on boxes and plastics, less so on anodized or textured metal surfaces.In particular, I tried using one as a seal between an anodized aluminum surface and a steel plate, and was able to peel it right off the aluminum with no marks left behind at all. This was after cleaning both surfaces with alcohol and letting them dry thoroughly.These are good for many applications, but not perfect for everything.

These work really well and there is no way I can see that they can be worked around. I sent out a lot of sensitive documents, and this helps assure that no one has gotten into them. Now if that happens, we will know and so will the recipient which gives everyone piece of mind.

I have storage bins for my move, perfect for security. Each 40gal storage bin now gets a tamper evident tag numbered for my inventory as I prepare for my move. I log each tag, what's in the bin on a separate sheet that has a corresponding number. This way I can keep inventory of what's in each bin and whether or not the contents have been tampered with. Plenty long enough to tag both the lid and bin body. Fast shipping.

Serial numbered? Check.Places for a signature and date? Check!Actually works? Check! (Yes, apparently this is an issue with tamper-evident tape/labels)This is a simple product, executed well enough. I've evaluated several comparable products - this is not the best performing, but the best performing was a rolled tape product, and this was much, much easier to use, and it did work quite well. For my day to day needs, this was where I finally landed. You can see from my photos - it works.The only flaw I can really call out is that the residue left behind when you peel it is white - so it doesn't show up as obviously on white paper (and sealing a white envelope is like the main use case for these, for me, so that's something).
