1"x3.35" Red Total Transfer Tamper-Evident Security Void Stickers/Labels/Seals with Sequential Numbers, Writable, Fan Folded for Convenience | 100-Pack

We use these for inventory control, as in we ship out a product to a customer that is "high value" where once it's opened, a restocking fee applies (due to the nature of the product). as such, we look for seals that show the packaging has been opened, or if it is returned without being opened, we can offer full refunds... that said these are Super sticky, leaves a great residue behind when trying to remove it. overall great value and individually packed which makes storing these on my desk a piece of cake. ( compared to others which come on a roll / sheet.)

these stickers do exactly what they promise. Once you stick them down, they leave behind that classic VOID mark if anyone tries to peel them up even a little. I tested one on a shipping box and they always leave a clean, obvious tamper trails when removed. The sequential numbering is a nice bonus if you're tracking inventory or shipments or something and the writable surface lets you add a quick note or initials for extra accountability. Adhesive isn’t gorilla-strong, but it’s not supposed to be! These are made to signal tampering, not hold your project together. If you need solid, no-nonsense security stickers for bags, boxes, or shipments, these are your new best friend! 🔐

Awesome tamper evident seal, works perfectly with any material it adheres to. Not easy to remove from glass either. It also shows tampering even with clean cuts with a knife so would need be peeled up without showing it. Great sticking power, clean look, inventory ready numbering, and only $15. Highly recommend!

Sticks pretty good and seems decent. So they work as they should and I'm pretty happy with that.

I have been putting these on shipments to make sure they stay secure and unopened. I tested them out before using them and it works. If someone tapers with the secure label, it's very noticeable.

Good. I tried some common mechanical removal techniques for this type of adhesive (which I'd rather not disclose publically) and the labels worked as intended, leaving a clear tamper evident mark. So I'd say these are working as intended. I found the adhesive to be relatively weak, so it's not intended to be a structural adhesive, but that's fine. It's only intended to be a tamper evident seal. Don't apply on top of non-tamper evident adhesive like I did on the picture - this was just to show the effect of the product. Overall it's a good product that works as intended

Secure snail mail items, tax forms, etc. Super!

been using this on mails to make sure the stuff stay seal. when writing on this, try not to touch it as you can wipe of the ink.

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!

Well, there isn't a whole lot to say about these tamper-evident security labels/seals except they seem reasonably well-made with typical quality and for the most part work just fine without issues. Note that the adhesive (thin film) layer underneath is REALLY thin (basically a thin layer of glue similar to those from glue tape rollers) and it's likely not able to hold anything in place with minimum amount of pressure applied to it (i.e. most deformed thin cardboards). That said, these do work just fine for what I need them to be, so there are no complaints there. ≡ Value All things considered, these are reasonably decent tamper-evident security labels/seals with typical quality and performance that for the most part work just fine without issues. They are somewhat reasonably priced at $22 (for 100 labels) for what they provide and their overall apparent quality, usability, versatility, and performance.

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 precut labels stick well and show clear evidence if tampered with. The serial numbering adds an extra layer of tracking, making them suitable for secure packaging needs.
