Review (5/5): EXTRA STRENGTH for feet.  Works "crazy good!"
The item came in a timely manner. I FINALLY used it after my shower, & it works crazy good. However, since it is professional strength, & the instructions state to use gloves. I did not use gloves. I carefully put it on my great toes, (wait 30 -45 seconds) then buff the callous. Did a great job! In hind sight, It may be advantageous to apply Vasolene to the surrounding skin. It did make the surrounding skin red, but not painful in any way. The seller may want to include that in their instructions, & also put a link in to order gloves. Maybe they can work out a percentage to them for using that company's gloves.
