Your feet go through so much every day and have never failed you, isn't it time you show them some love? Amope Pedi Perfect Electronic Foot File Refill aims at making your feet look and feel great with every step you take. The specially designed Microlumina roller heads are long-lasting, designed with micro-abrasive particles that buff away stubborn hard skin. The extra coarse refills help in removing stubborn hard skin by exfoliating the foot via a light rotating action to reveal touchable soft and smooth feet. Gently rotate the file over hard skin and see how easily hard skin is removed. It spins 360 degrees for quick results on thick, hard skin of feet. With Amope, fall in love with your feet! How To Change the Roller Heads: Remove the roller by pressing the eject button on the side of the unit and gently pulling it away. Press in the pin on each end of the roller head to place the new one, slide the head between the tines of the Foot File until the pins align with and snap into the holes in the Foot File. Caution: Use only on dry (not wet) skin.
