Thermal Paper Data Protection Fluid,Privacy Protection Parcel Opener, Security Stamp Identity Protection Roller Stamper, for Personal Information Blackout,Package ID Blockout,Theft Protection. (3Pcs)

I typically use a heat gun to weaken the adhesive of shipping labels, peel them off, attach them to a piece of scrap paper and then put that paper into my shredder. Most thermal labels just turn white with this applied, although I have run into a couple that this liquid doesn't seem to have much effect on. Still, if nine out of ten labels work, that's good enough for me and saves a lot of effort.

This is the 2nd shipment of this product and again it’s all water. If any coverage ink was there it came out in the bags. Each time the inside bubble wrapped double bagged products were wet /had a chemical smell and still produced nothing but a wet line on paper.

So it did leak a bit (probably from the flaws of the cap design) when I got it but no worries. I washed it and took it out of the packaging. There's still alot of liquid inside. When you use it, you have to press down and rub it then whatever is on the thermal paper/label will rub off. I find myself pressing while rubbing and it comes off in 3 rubs. Works pretty well since I can't get the labels off of the packaging.

This really works. You have to rub it a bit with the applicator tip.Great to keep your address private.

Not sure if I don’t know how to use them, I can’t read the chinese instructions and no pictures to follow how to use it, when I use it only water comes out. Do I have to shake it first? I might return these product.

Worked well. All info disappeared
