Thanks for your input, having never seen or heard of these before just had me interested.

I bought some a few years ago when I first starting making the window frames for my Fairey builds using plastic sheet. I don't use them very often as they are very fine and I tend to use my diamond needle files more as they contain round ones for the corners. Always handy to have in the drawer though.

Yes, I have decided to get them when I go back to the store. I googled glass files and apparently they are used widely in the manicure business.
Thanks

Any kind of file for tight spaces is worth taking a chance. Also for buffing small parts. Def buy them and give them a shot.
