We ordered these because we resell items found in storage units including electronics. To avoid falsified returns and scams where buyers take parts that they need from a working unit and then submit a return, these came into play. They work exactly as intended. Once applied it’s immediately obvious if they’ve been tampered with. The adhesive sticks well to the plastic housing around all kinds of electronics. The void transfer shows clearly when removed and I like that they’re sequential numbered and rideable, which helps with tracking. The size is practical without being bulky, and the pack comes with quite a bit, making them a good value for and worth using on electronic items sales.

I am a chief mixologist at work and perform lots of R&D. I have been using regular electric tape to seal the caps of pre-batched cocktails or in-house made syrups or boxes of speciality garnishes. However, with these tamper-Evident Security stickers, no one will even think about tampering all the work I put into. It works great for me as a preventative measures as once applied, quite visible "TAPERED" sign will appear if the tape is peeled. It will work better on the hard surface, not paper surface as it may tear the top layer of paper and the the word "TAMPERED" will NOT appear.

Review: Blue Non-Transfer Tamper-Evident Security Void Stickers When you have sensitive equipment to shop, often you need to indicate to the recipient that the box or case hasn't been opened while in transit, and these seals are for just such a use. In my avocation, I fly drones for the US Government (not the cool big ones with Hellfire missiles, but the smaller, friendlier ones that have infrared cameras for finding lost hikers and downed aircraft). Sometimes, I have to ship or transport these drones around the country, and when I do, I need a method to seal the case. These stickers are an effective, economical method for ensuring that if the case is opened during transit, the recipient will know immediately upon receipt. They stick to ABS plastic cases quite nicely. They also stick to the polypropylene used for evidence bags, sandwich bags (for the fridge), paper envelopes, shipping boxes, and The trick is that parts of the stickers adhere better than others, and the very sticky parts spell out words like "OPEN," "SECURE," and "TAMPER," when you peel off the sticker. The stickers are bright blue (I haven't checked to see whether they fluoresce, but it wouldn't surprise me). Once they're attached, you can't really move them without making a serious mess of the label and its uniform blue color. The labels have a location for your signature and the date (Pro Tip: Sign and date them before you use them to seal a package - afterward, your writing may be very messy). That information is on the surface, so even if the seal is tampered with, the original seal signature and date are legible. Summary: These are great for putting a "proof of non-tampering" on equipment cases, suitcases, evidence bags, envelopes, crates, and the like. They are priced reasonably, and do a great job of ensuring that your shipment/letter/evidence hasn't been tampered with since it was sealed. They do a great job at what they're designed for. 5 Stars.

The Blue ones dont stick as well as the red ones. You can restick them back on. The void is rarely noticeable

This is a really good security seal. I can't quite say great because I've seen the application applied in different ways that I enjoy more, but this is really good. The stickiness will adhere to most surfaces and if using cardboard it's enough to take off the top layer. The logos strip enough that you can see it but you have to glance at it. I prefer it when they leave a residue on the item but if you're putting it directly on something it would make sense that you don't want that. It's functionality is exactly what you want it to be in that's a great thing. The pack feels like there are hundreds of them so unless you have a shipping business you will not run out at any amount of time. Really great value for the average person and the security not
