I use it instead of hairspray on my ender 3 pro 3d printer, it helps the petg to stay stuck to the bed. It's much better and more economical than hairspray, and it cleans much easier.

I bought it for my 3.5-year-old daughter to use, and we both were very excited. She can stick whatever she wants, and I don't have to run around collecting glue from everywhere! Even if she pulls it with force, it doesn't shoot out like in other packages. If by any chance the cap goes missing for a while and the tip dries out, if you rub it with a damp cloth, the glue cleans and flows again.
