Great value for money

### ⭐⭐⭐⭐ Good

1mm but the stem is even finer. I broke a couple to start with, but ok.

### ⭐⭐⭐⭐⭐ Perfect for seaglass
*by C***W on 25 December 2021*

Loved these drills, they are small enough to drill sea glass, what I bought them for, and use clasps I bought on Amazon too! I go to craft fairs and sell these so wanted some drills that last for a good while and these do, plenty of holes per drill! Will definitely be buying these from this supplier when I next need new ones
