Customer Reviews
I bought the bit cooler set and loved them. I needed some bigger sizes so I got these as well. The description said they come with a case and what I got was a plastic roll-up pouch. For $145 I'd hope for a real case. The cheaper grade bits come in a nice metal case, why not these too?
