CHAOYUELYF 1200 Pieces 45 x 30 mm Clear Perforated Shrink Bands Heat Shrink Wrap Film Shrink Seal Bands for Essential Oil Bottle, Dropper Bottle and Test Tube Bottle Cap Diameter 3/4 to 1 Inch

Very easy to use. Doesn't take more than a few seconds of heat to fully seal and is simple enough to tear open. They work as great tamper seals especially if you have a small business and sell bottles. They're also ideal for keeping any liquids from leaking when traveling. I usually secure my skincare bottle lids with normal cellotape, but I really don't like the sticky residue it leaves behind. This is an effective and convenient alternative. I use tweezers to hold them in place while heating using a hair dryer so as to not burn my fingers. Great value for so many pieces so I'd happily recommend.

There's not really much to say about this you get of course a bunch of different sizes as well as lots of them so you can be doing this for days on end and it's very well made very well designed it fits great as well for whatever you need it for its initially shrink wrap so kind of heat it around and it just wrapped up against the product that you've actually covered overall the quality of materials perfectly it doesn't really burn I have to be very careful with it though 'cause I don't wanna burn your hands or anything you kind of just leave it there and it just shrink wraps itself overall the product is great it's very well designed very well made very easy to use and I haven't had any problems with it so far.
