01
Sand the loose edge. Leave the hard-earned callus.
Don’t let a loose edge choose when your session ends.
Callus is useful. A raised lip is not. Flapstopper lets you take down the part that catches while keeping the skin you built underneath.
Level it
Work only the raised skin.
Use light, controlled passes until the lip sits flush with the surrounding callus.
Leave it
Keep the useful layer intact.
Stop once the catch point is gone. The goal is maintenance, not starting over.

A raised edge is easiest to fix while it is still just an edge — before it catches, lifts, and turns into a flapper.
Your callus is useful. The raised edge is the problem.
Old habit
Sand the whole pad flat.
Clear answers for better skin days.
What makes Flapstopper different from sandpaper or a nail file?
Sandpaper and nail files can work, but they are easy to overdo. Flapstopper is made for controlled climbing skin maintenance: smooth the raised callus edge without turning your whole hand into a sanding project.
How often should I use it?
Use it after sessions or whenever raised callus edges start to build. Think light, regular maintenance — not aggressive skin removal.
Which grit should I use?
Use 80 grit for rougher buildup, 100 grit for regular maintenance, and 180 grit for finer smoothing. Start lighter than you think and remove less than you think.
Can it prevent every flapper?
No tool can promise that. But Flapstopper helps reduce one of the main causes: raised, uneven callus edges that catch under force and tear open.
Should I use it before or after climbing?
For most climbers, after climbing is best. Rough areas are easier to spot, and you can smooth the risky edges before your next session.
Can I use it on torn, bleeding, or painful skin?
No. Do not use it on open wounds, bleeding skin, raw flappers, painful split tips, or skin that feels sensitive. Flapstopper is for maintenance before damage happens.
Start with better skin decisions.
