Electric Nail Clipper Simply place your fingertip on the nail-clipping head. The roller rotates and shaves the nail. Also suitable for caregiving, etc. - Included: Cleaning brush for the roller - Batteries not included (requires 2 AA batteries separately) Manufactured by: Rosenstar Co., Ltd. (Kawasaki, Kanagawa Prefecture) Purchased at Bic Camera. I categorized it under foot care, but it can also be used for fingernails. However, the finish may not be very smooth for weak or fragile nails, so you may need to polish them separately with a nail file (nail file not included). Thank you for looking.
