Transparent Blank Tamper Evident Labels Crystal Clear Sealing Package Seal Self Adhesive Security Warranty Void Tamper Proof Stickers (500pcs Round)

These have been great for me. I use them to help potty train my son. We use cloth diapers and I was looking for a way to replicate the moisture indicator strip on disposable diapers but, without buying new cloth diapers (which seems silly now that we're potty training), I couldn't find anything made for cloth diapers. Then I started thinking of other potential solutions and ended up here. These give me all the information I need (without constantly having to feel for pee) and enable me to give my boy an extra reward every time he makes it back to the potty chair with a dry diaper 😊 The stickers are already small, but I actually cut them into quarters to increase the value. The tiny bit of sticker still releases more than enough dye to make a wet diaper obvious. The one thing is that I'm not sure how I'd feel about putting them right next to his skin. I mean, it would probably be fine, and the dye does get to his skin, but hasn't been a problem. I don't have to worry about the sticker being directly on his skin (or potentially falling off of the diaper and working its way into an orifice) because we use disposable bamboo liners to catch poop, so I put the stickers under the liners.

Works. Exactly what I was looking for. Have these stuck on a bounty placed next to my sump pump. So I know if there is water. Very hard to see water on a tile.

Perfect. QR code works perfectly. Exactly what I wanted.

These stickers work. Easy to verify water leak.

As described. I used sharpie to write on them with no issue. I tested one and the tamper underlay was very visible

I would not buy these again because they are too easy to take off without tearing. They need to have a perforated line so if somebody takes it off, you would be able to tell.

I am using this to check for leaks in the plumbing under the sink. I wrap paper towel around the shutoff valve and place a sticker on the paper towel. When the paper towel gets wet, the sticker turns red.

Before using these to seal a package with an expensive device I was sending away for repair, I tested one on another cardboard box. It failed miserably; even after trying a second one and rubbing it vigorously in place it peeled back off like a Post-It note instead of security tape. It left absolutely no printing on the box at all. Go for the brand, which actually works. These are worthless.
