Chtep Tamper Tamper Evident Stickers, 100% High Residue Tamper,Evident Security Warranty Seal, Void Stickers, Security Labels, (Serial Number 0.8 * 2.4inch,Red 100PCS)

Great product. Have to take care putting them on packages. If you accidently touch the sticky side the tamperproofing will come off onto your finger. This is actaully really good as it shows it's impossible to tamper with it.

I was running out of tamper proof tape and this works great as a replacement! Thank you.

Very sticky to seal a box or a pail.

These were a bit smaller than expected, although they do have plenty of measurements in the description, so that isn't really the seller's fault. I have other ones previously ordered that were larger and I though these were pretty much the same thing, but they are still decent sized, probably better for letter size envelopes or small boxes. I tried one and it didn't really seem to stick too well to the cardboard, and when I removed it, most of the tamper part also came off, although some did remain. It's possible trying again and pressing harder would help. It is still obvious that the sticker has been tampered with, so they do work.

This is a great pack of tamper stickers and they work just as they should. Sadly our reason for getting these is that we have one of our children that we are working on with impulsive sneaking of food or getting into things that he shouldn't. It didn't take many times of seeing that these work (never fully opened one but see several things that he had STARTED to open) for him to stop trying.So obviously in any tampering situation I think these would work great as they're not easily beaten.100 for this price felt very appropriate to me.Also, water/steam/heat resistant in terms of defeating tamper detection.
