About

Surfers get price-gouged by a duopoly. We exist to break that.

Fin Blanks makes quality fibreglass surfboard fins in colour. Different shapes, different feels — twins, keels, longboards, quads — at fair prices, shipped worldwide. New fins make your board feel new, and that's way cheaper than a new board.

The brand is built around one idea: different is fun. Try a colour you haven't tried, a shape you haven't ridden. Most fins look the same. Ours don't.

What we make

• Single longboard fins for noseriders, pivot turners and traditional logs
• Twin and keel sets for fish, mids and alt-craft
• Custom colours and shapes on request — minimum order 5

How we ship

Most fins are made on demand and ship in 7–14 days. In-stock colours ship in 1–2 days. Free shipping worldwide on orders over $150. Standard tracked delivery, no extras at checkout.
