Query: Not Sure if Gross or Rewarding

This is simultaneously the most gross and rewarding item I've ever purchased on Amazon. I thought the electric foot buffer was gross because it got powdered dead skin everywhere, but this? This is some legit snake molting cosplay realness. Summer and sandals have not been kind to my feet and I had a lot to give. It takes about a week to REALLY get results, but when you do, prepare yourself. About 3 days in my husband was already gagging at the sight of the results. Me? I'm a Biology teacher and thing it's fascinating! I haven't tried another type of these so I don't know how they compare. What I do know is that I've tried other callus solutions and nothing has ever been as dramatic as this. It's time consuming but worth it.
