<P>PROBLEM TO BE SOLVED: To provide a pumice that reduces processing time of removing keratin by enlarging an area in contact between the heel and the pumice. <P>SOLUTION: A U-shaped deep scraped part is prepared in a prescribed part in the end face of a solid pumice, thereby enlarging the area in contact between the heel and the pumice. Thus, a time for foot care is reduced, and partial care of the heel by dividing in several times is solved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
