WELSTIK Tamper Tape Red Tamper Evident Security Seals Tape, Transfer Tamper Proof Security Void Tapes (Red, 1.88 inch x 55 Yards)

Works exactly as advertised.End is easily found each time & peels away from roll very smoothly. The adhesive is sticky enough to do its job on paper, plastic, wood, metal, virtually anything. The tamper evident marks are always left behind & there's absolutely no way to hide it once the tape has been tampered with. What's worked for me for clean-up is an oil based cleaner or an alcohol based cleaner.

There's a learning curb on how to properly handle this tape. Don't use it in a warm or hot environment. The adhesive will stick to your fingers — a lot! — so there will be a significant amount of wasted tape until you perfect your handling technique. Other than that, this product worked perfectly as shown and described. (I know that because Customs tried to pull off the tape and put it back on)

I got this for sealing plastic boxes of baked goods from being gotten into. The frozen ones don't stay very well and can be peeled completely without the "thank you " being left behind. The room temperature is better, but you REALLY have to press it down to make it work. On paper products, it's great.

I use this to seal deposit envelopes after I cash out registers. This is a very useful product.

Although this tape holds well, it really only provides a false sense of security. If someone is going to tamper with your package, they most likely are not going to rip the tape off. They will most likely cut the tape with a knife. I also was able to remove the tape with a hair dryer which prevented the "VOID" message from appearing on the box so was easily defeated. I was also using this tape with a tape gun and when cutting the tape with either the gun or a scissor, I had to clean them because it left the void message on both the scissor and the tape gun. Tape was more of a hassle to deal with than I had hoped and if you can peal it up with a hair dryer without leaving a "VOID" message, I no longer see the value in this product. I'll probably choose something like Amazon uses to seal their boxes which I believe requires water to activate and has a fiber glass type material embedded in it.

Love it works great

I followed the exact instructions on the video, and the void part showed on the tape, but not on the box. For about 3 inches it worked the way it was supposed to then the rest of the tape firmly just came off the box leaving absolutely no residue. This is a garbage system and the tape does not work and if you’re buying it, you’re just wasting your money.

got this for a prank on a co worker and we later found out there was nothing we could do to remove the void words. so it works great but its nearly permanent at least on panted metal
