0.59 in High Security Tamper Evident Seal Warranty Void Original Genuine Authentic Hologram Labels/Stickers w/Unique Sequential Serial Numbering Tamper Proof Stickers (550)

They are pretty small. Roughly dime sized. Would have liked to have them be a little bigger, but they work all the same. I tested these on a few different materials (envelope, cardboard and bubble mailer) and they worked as I expected. I use these because I've been shipping out TCG singles and even though the envelopes I use would already show signs of tampering, I wanted an extra layer because I know how crazy people have been getting over TCGs and package tampering. This should give a little more piece of mind to my buyer when they receive their mail.

excellent

Perfect

It works well for my equipment repair business. Due to warranty issues, I needed these security seals.

They were smaller than I expected. They seemed to work good at first, but when the temperature dropped outside, several of them came unstuck (some left behind marks to make it look like they were tampered with, but some didn't and just came unstuck). If you need it for security, look somewhere else.

These labels come with sequential numbering. Very nice quality. You pay for the immediacy of getting the product with amazon prime. Can you purchase cheaper in bulk elsewhere? yes. But these are great for small projects and decently priced. Adhesion is good. Tamper proof works well.
