ChtepTamper 100 Pieces No Transfer Tamper-Evident Stickers Security Labels Great for Goods Shipping,Exchange of Agency Files, Privacy Protection or More(Serial Number 0.8 * 2.4inches Yellow)

Good quality buy cost isn't that great

The media could not be loaded. Very hard to see the "Void" on these yellow , small stickers.I like that you can date and sign them.Left residue on the sample tape on the envelope they came in. Hmmm.

Can't complain everything works like it should I even test the label and it does what it says

Great product, but not the best of you have relative humidity over 50% often during times/locations of usage.

This is perfect for home businesses that ship items. I ship hundreds of vintage items a year and these stickers help discourage false return request. You receive a significant amount for the price which I really appreciate.

Adhesiveness might work on paper but will not work on a smooth surface such as plastic or glass

Pros: Decent size; sequentially numbered; space to write date and signature; sticks well; very visible tamper evidence.Con: leaves no marks behind, so if the label is completely removed, cannot tell it was ever there.I've had some shipments that I sent out arrive with missing things or even a completely different item in the box, so I started using tamper evident seals to make sure my boxes are delivered the way I packed them. This has worked out great so far--not a single package has been opened and switched around since I began adding them to my packages. Those stickers, however, left visible "void" marks if the label was lifted up, letting you know the box had been opened. These labels peel away clean, so anyone along the mail route who wants to interfere with the box only need remove the entire sticker to get away with it. I do like the stamped numbers on each label to keep track of stuff, and the ability to sign and date each label is great too. You need to keep a record of what has a label, which number label, etc, for these to be effective, plus you would need proof, such as a photo, if the label is gone. That is an extra step I don't want to deal with for my bulk mailings. For things like lab jars, or keeping the kids out of the cookies, these are perfect.

I've been using these on a number of surfaces, and most surfaces I put them on don't have proper adhesion. These aren't particularly unfriendly surfaces, other stickers stick just fine. Especially when trying to go around a corner, where a seam is often located on a hatch that can be opened, one side usually comes off and lifts away -- defeating its own 'security.' It doesn't void when it comes off over time either. So it presents an attack vector in which someone could tamper with something after the sticker peels itself away, then press it back down and have no indication that anything was accessed.Things like PC case sheet metal for servers and network equipment, which this should be well suited for, don't get the proper adhesion, and thus these prove unreliable.Another complaint is that the barcode and serial number is printed onto the top of the sticker, and after having one on the bottom of my laptop for no more than 10 days, it was barely readable.Those complaints aside, for the surfaces that it does stick well to, it does its job. None of the stickers have left any residue when removed, and they all void out when deliberately peeled off -- it's just that if they come off slowly by themselves, they don't void.
