Hapstone silicon carbide powder set for stones leveling + mirrors

So far, I have only used 80-grit to resurface a T2 150 boride stone. It worked perfectly and quickly. I was afraid that the surface area would be a little small (only 20 cm x 20 cm for a stone 15 cm long), but in practice it is sufficient.

I really like this set! It was a pleasure to work with it with my Hapstone Premium CBNs.
