500pcs Void Hologram Security Stickers, Tamper Evident Warranty Holographic Labels, Unique Number（1 inch x 0.3 inch WZRYSEAL）

Sticks good.

These work well, I apply them to goods I sell on ebay to verify that the item is what I am selling in case of warrantee claim.Just be careful when installing them. just pressing them in your fingers will cause the tamper to trigger.

Doesn’t adhere well

I purchased a lot of these they do not stay on the bottles they peel right off the next day don't waste your money on this product

Perfect size and great value for how many you get.

It is very easy to accidentally void one of these stickers. If you are used to using void labels you are probably used to accidentally voiding them because that's just part of it.It can be quite annoying for packaging if you aren't careful with them. However, that's the point of the product. So learn how to apply them well or teach your employees how to if you have issuesI will say these stickers WILL NOT STICK well to SOME types of hard plastics. If there is an offset on a product (awkward gap or space between the lid/opening of the container and the container itself) this product may have issues if its a hard plastic. However, if its flush, it shouldnt be an issue.This product WILL STICK EXCELLENT to paper, soft plastic (bags), and some types of cardboard. (not waxed cardboard)
