These pedi roller refills are supposed to fit into the Pedi-Roller callus remover. I didn't realize at the time that this review was only for the refill pack. I don't own the item so I can't tell you how well they fit in the gadget, but I can tell you that just by touch, it appears that they would work really well to remove dead skin and callus' from your feet. I guess now I will have to by the roller so that I can actually use them...lol.
You can get this item Here on Amazon.
I received this item for free or at a discount for my honest review.
Have a great day!
