Its Pinhigh Direct division makes premixed lapping compounds, sold in the same store as “Pinhigh Lapping for Homeowners.”

Who it’s for

Rock tumblers, beginners and experienced alike, who want graded silicon carbide grit by the 5 lb bag, tumbling polishes (cerium oxide, tin oxide, micro alumina) and starter kits. It also suits clubs and teachers buying grit in bulk.

It’s the company’s own store with a working cart (PinnacleCart, cart at /index.php?p=cart), “Add to Cart” buttons and printed dollar prices. The About and Terms pages list its address, phone numbers and terms. It is not a marketplace, not Amazon and not an affiliate storefront.
