Callus Peel Starter Kit. 10 Complete Treatments. This 15 minute four-step system includes skin-softening patches that are wrapped around the bottom of the foot to soften the skin, a special scraper device to peel off the dead skin callus, followed by a third step to polish the remaining keratin. The treatment is completed by applying moisturising cream. ALL four items are included in this kit. An easy and fast process.
