Outstanding.
When placing my rather large order (8 CBN Premium stones, 3 strops, diamond emulsions, case...) - I inadvertently missed one of the stones I wanted, instead mistakenly ordering another stone twice.
Reviewing the Hapstone confirmation email, I spotted the error: Yikes, now what? No phone number, so I wrote to Info@Hapstone and was pleasantly surprised when "Mario" immediately wrote back and said he would correct my error prior to shipment - no problem. So - great service!!
