Roll Products 113-0002 Transparent Secure Lock Label, Legend "Tamper Resistant", 2-1/2" Length x 5/8" Width (Roll of 500)

General observations on product: Box says "Made in USA" (nice), measurements are pretty close: I measure each tape at about 5/8" wide x 2.25" long. Tape "labels" are on a roll, more or less as pictured. Each label says "TAMPER RESISTANT" twice (once right-side-up, once upside down). Labels are made of a very thin, clear plastic film with a fairly aggressive adhesive on one side. They peel off the roll easily, and are easy to stick to most smooth surfaces. Will add photos to this review if I can.I wanted these to try and seal some small cardboard boxes for retail, to show if a buyer had opened the merchandise (thus voiding a return). But I also tested them on envelopes, and a painted file cabinet to see if they might work in any of these applications. They stuck very well to any of these surfaces. Trying to peel them off a day later - using a razor blade and much care - I found you CAN peel them off, open the item, and then stick them back down again, and they will look almost as if they had never been touched. Being very thin, I often tore or split the tape when peeling it up, but with a little more care, you can do it without breaking. When you peel them up, they leave behind a very sticky residue (which you can use to stick them back down again). If you look VERY closely (like with a magnifying glass) you can probably tell the seal has been tampered with, but that would not be easy.So, in the end, they are not perfect. Against a determined "crook", they can be tampered with, leaving behind almost no trace. But for casual, lower risk applications, I think they are still useful. If someone is thinking about opening a box or envelope, and then saying that they did not, this should make them think twice. For the cost, it is a reasonable deterrent.

This product does not have any tamper resistant features. It is easily removed in one piece. It is basically a pre-cut strip of tape with “tamper resistant” printed on it. I use them to tape up holes in plastic bags, keep cereal boxes closed, on envelope flaps, etc. If you need these for actual security, like maybe on a credit card reader or computer housing, AVOID.

The tabs are readily and easily removed without tearing them. They can also be reapplied to the surface. I found these useless for prescription bottles. A paper product might have better luck with them but they were not tamper evident for my application.

This "security tape" does not tear. You can peel it right off and then stick it back on with little evidence that it had been removed. For what I need this for it is, in a word, worthless.

The adhesive is poor and there is nothing to indicate when the item has been tampered with.

This is nothing more than a standard clear label. The are no tamper-evident features. The description claims it will break apart if an attempt is made to remove it. That is a total lie. Don't watste your money.
