Sopečný černý pemzový kámen

I've been through a bunch of those cheap foot files that just skate over calluses, but this coarse pumice actually bites into the thick skin on my heels. A few minutes in the shower and my feet feel noticeably smoother, and the rough texture hasn't worn down at all after a month of weekly use.

My heels were like sandpaper before this, and the coarse volcanic texture really bites into the dead skin without feeling like it's shredding me. Used it in the shower for a few minutes and my feet are honestly smoother than they've been in months.

My heels were like sandpaper before I tried this, and the rough volcanic surface genuinely buffed away the tough patches in a few minutes. It’s solid and easy to grip, so I can scrub my feet without it slipping in the shower. Regular use has kept my skin noticeably smoother for weeks now.
