Query: Well worth the investment

Luxury Foot Treatment DuoThis item was well worth the price that I paid for considering how much problems I have with cracked and dry skin on my feet ever since I was 12 yrs old. The file stands up to much use and the foot cream is wonderful. Sterilizing the file is easy after use--simple rubbing alcohol is all it requires. I have to admit I overdid it the first time but afterwards no problems, wonderful product along with the nail file that I have also purchased from the same line. If you have problems with cracked heels or dry/callused feet and worry about using skin razors to solve the problem, give this a try.
