What climbers are saying

★★★★★

Bought this before a climbing trip and ended up using it every night after climbing. My hands definitely felt better the next morning.

I climb indoors three or four times a week and my hands were constantly catching up with me. Flapstopper has made it much easier to keep climbing consistently.

★★★★★

I forgot to pack it for a weekend climbing trip and immediately noticed the difference. That was when I realised how much I had started relying on it.

★★★★★

Really simple product, which is exactly what I wanted. No ten-step routine, no fuss. I use it regularly and my hands have been much easier to manage.

★★★★★

My first one was recommended by someone at my local gym. I now have a second because I kept forgetting to bring it with me.

★★★★★

I wanted something made with climbers in mind rather than another generic hand product. Flapstopper has been a great addition to my routine.

Catch it early. Climb longer.

You know the feeling. One rough edge starts catching mid-session and suddenly it's all you can think about. Flapstopper smooths it down in seconds — before it turns into the reason you're sitting the next one out.

Notice the edge.
Smooth it.
Leave the rest alone.

Made for the bag. Built for the wall.

Clear answers for better skin days.

Why use this instead of sandpaper?

Sandpaper works. Flapstopper gives you selectable grit, adjustable speed and a repeatable way to work only the raised edge.

Which part of the callus should I work?

Focus on raised, hard or uneven edges that are likely to catch while climbing. The goal is to smooth the callus, not remove it.

Which grit should I start with?

Start conservatively and use the finer grit when you are unsure. You can always remove more material gradually.

How often should I use it?

Use it when raised or rough callus edges begin to develop rather than waiting until they become large enough to catch and tear.

Does it prevent every flapper?

No method can prevent every skin tear, but keeping calluses smooth can reduce the raised edges that are more likely to catch.

Can I use it on torn skin?

Flapstopper is intended for maintaining intact callus and rough skin. Avoid using it directly on open or freshly torn skin.
