Our Story

Built on the Wall. Perfected by Skin.

We know that sickening feeling. You're mid-crux, pushing through the sequence you've been projecting for weeks, when it happens—that unmistakable tear of callus pulling loose. A flapper. Session over.

We've lived it. From Danish Climbing gyms to granite walls around the world, our founders got tired of ending sends with ripped skin and days off the wall.

We looked around for solutions. Tape was temporary. Drugstore files weren't built for tough climber skin. Most "solutions" weren't designed for the demands of real athletes.

So we created our own.

Made by Climbers, For Climbers

FlapStopper was born in Denmark, shaped by our climbing community and perfected through countless sessions on stone and plastic. We're not here to sell hype—we're here to solve a real problem that every climber faces.

Our callus removal tool is precise, powerful, and built from first-hand experience. It gently files down hardened skin to reduce your risk of flappers, keeping your hands smooth, strong, and session-ready.

No gimmicks. Just smart gear that works.
