I have a Korstone vanity top and want another. No luck at H.D. The comapnys mailimg address was 2564 Moores rd. Seaman, Ohio 45679 Phone was 1-877-korstone. They also had a florida number: fax:561-671-5922. Korstone trademark is registered to E.H. Enterprises.LLC. If anyone has any luck with this please post a reply.
