FirstZi 2 Inch Diameter Clear Circle Wafer Tamper Seal Labels, Waterproof, 500 Round Stickers per Roll, Perfect for Envelopes, Box, Gift Packaging, Shipping Carton

I love to use these when I deliver food. They work great to keep drinks from leaking. Are also great to seal bags up.

I covered my labels my canned goods so when the get wet they so t run and smear.

I like that it's two inches and the adhesion works well.

The quality and durability of these stickers is way better than I expected!

It doesn’t hold cardboard boxes when a small piece of packing tape does. May work fine if you don’t need strong adhesive.

Great adhesion and crystal clear look

Even when you are selling open box items, it's nice to place everything in there neat the clean, and use one of these labels for that factory sealed look. They are completely transparent, and the glue is strong enough on the surface to hold onto the box and prevent it from opening. They are waterproof which is important for something that may wind up on someone's doorstep.Each one is parked on the backer roll, and each one has a perforation on that backer roll making it easy to tear off one without having to carry the roll over to your project. You can tear off one, or as many as you like.If you are selling something that has a return policy only for unopened products this is the label for you. Even if they use a heat gun to remove it, there is no way it can be reused and not be detectable that it was removed. The roll isn't that large so it takes up very little space in your tape drawer. A nice addition to your arsenal.

These are great seals for the value and they work well. I use these for sealing cardboard and cellophane envelopes. They are about the size of a half dollar. Will buy more when needed.
