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.

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 sequential numbering printed on each label is another useful feature, making it easier to organize and monitor multiple sealed items, especially in inventory control or asset management settings. The fan-folded packaging makes the labels simple to dispense and keeps them neatly organized without the hassle of managing a roll. The surface of the labels is smooth and writable with standard pens or markers, which ensures that handwritten notes remain legible and smudge-free.

They’re ideal for situations where traceability, tamper evidence, and clean removal are priorities.

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

Comes in a huge pack of 100 stickers, decent adhesive stickiness. I used these on my eBay packages (on cardboard boxes) and they work very nicely. Removing them from the box separates the adhesive side and indicates that the package was tampered with. The sticker itself is pretty durable. Wrote with a sharpie on them and doesn't smear.

I recently had the opportunity to test out these tamper-evident security labels, and they get the job done well. The first thing I noticed was the strong adhesive. These labels stick firmly to a variety of surfaces, including paper, plastic, and metal. I tried peeling them off, and as advertised, they leave behind a "VOID" marking, making it clear that the seal has been broken. This is particularly useful for ensuring that high-value items remain secure during shipping. The sequential serial numbers on each label are a nice touch, adding an extra layer of traceability. The labels are easy to apply and remove cleanly from the backing, which makes them user-friendly. However, I did find that the "VOID" markings are connected rather than individual, which could make it slightly easier for someone determined to tamper with the seal without leaving obvious signs. Despite this minor drawback, these labels provide a solid solution for basic tamper-evident needs and come at a reasonable price point. Overall, if you need reliable security labels these are definitely worth considering. Just be aware of the size.

These red, serial-numbered security labels are thick and durable, making them ideal for high-value shipments or secure packaging. The 2″×6″ size is perfect for sealing boxes and ensuring any tampering is instantly noticeable. Once removed, the “VOID” pattern transfers completely, providing clear evidence of opening. The precut roll makes application fast and easy—no fuss with scissors or mismeasurement. A reliable and professional solution for anyone needing strong tamper protection!

Amazing seal tape labels that provide great security when shipping items to ensure that the package has not been open or tampered with. For the price it is worth it just to have that assurance that your packages are safe and are only opened by those who are suppose to.

I got this to put on mailings that require basic tamper evident packaging and find it works very well. It applies like a normal sticker but no matter how you try to peel it, it will leave the void marking behind. I tested on many different media types and even on smooth surfaces it works well. Using a heat gun or putting it in the freezer also do not substantially increase "infiltration" rates. It does one thing and it does it well. Thumbs up.

These are great security label all comes with a different serial number. The glue is strong. I have try to stick on paper, plastic or metal. It do leave the void words on the other side after I remove this security label. There is no way you can reseal your label once the label has been open. Both the label side and the seal surface will have void mark on it if it has been open. The transfer is very difficult to remove.
