Yes, absolutely — this honing oil can be safely used on all Hapstone stones.
✅ CBN Start Kit & Diamond Start Kit – completely fine, since these are non-porous stones (oil stays on the surface and can be wiped off).
✅ Hapstone Ruby Red – also compatible, works very well with oil.
So yes, it’s a great option for all of them.
