Review on 💎 Exquisite Diamond Jewelry Shells: Gemstones Pieces & Cutting Tools Collection by Avery Sharma

I use them to make stained glass earrings and buy them several times. When I first ordered them I would say that 90% of the bits worked beautifully and I got a lot out of them. Next time I'd say about a quarter of them were unusable, the tips weren't fully covered to the point of not even biting the glass surface to start drilling - a little frustrating but at a cost beyond the I really couldn't complain. Only 4 of these were of decent quality when I last bought them and even that didn't last for more than 20 holes. I hope this last purchase was a godsend in terms of quality and I will take a chance and buy again as these bits are exactly what I need, just wish they were more consistent.
