Hello neighbors. I over-bought these Dremel diamond bit kits when I was working on artwork that required me to drill holes in glass. I only used one of the kits, the rest are brand new, unused. (I realized that only one specific diamond bit worked for what I was doing, and instead of using these kits, I ended up ordering many of just that particular one, to finish the job.) Perfect Hannukah gift or stocking stuffer for the hobbiest on your list! Each kit costs at least $6, but I'll let all 5 go for $15, OBO. Contact me if you are interested. Thanks. -Becky
