I'm selling this item because I received it as a gift but have no use for it (❁ᴗ͈ˬᴗ͈) The outer box has some minor stains, but the product itself is in very clean condition as it's completely unused except for being taken out of the box to check the operation. Retail price: 3500 yen + tax [From the website below] ■ Product size Weight: Approximately W7.6 x D4.6 x H16.8cm / Approximately 164g ■ Material Body / ABS resin Roller cover / PC resin Roller file / Alumina (artificial diamond powder) ■ Individual packaging size Weight: Approximately W78 x H171 x D47cm / Approximately 177g ■ Batteries used: 4 AA alkaline batteries The delicate-grained roller with diamond powder turns hard calluses into powder. If you press too hard, it will stop for safety reasons, so it's sufficient to rub lightly. Always use on dry skin. The easy-to-grip shape makes it less tiring, and the ON/OFF operation is simple with a single button in the center. Battery life is approximately 40 uses when used for 10 minutes each time (When using domestic alkaline batteries) If you feel it's become difficult to file, it might be time to replace the roller. Please check if the sparkle on the roller surface is gone. ★ I have read through everything, but there may be minor oversights. Please understand that this is a personally stored item, and only those who can accept this should purchase it.
