i've never scrapped them either, at least not intentionally!! I have them all over my tool boxes and a bunch at my dads too. they come in handy for sooooo much stuff. I keep one on my vices to catch small pieces that might happen to fall that way, I keep them on my workbench to stick screws to I am going to use again for say a monitor and they are handy for sticking tools to all over the place when working on a mower or something outside or anywhere not near a work bench. but, I've also lost track of them and scrapped them when they were left stuck to something I planned on scrapping and off my truck bed too that way so good thing I have bunches of backups!
