Thank you for viewing. This is an electric nail file for babies. (Although not Combi brand, it's a similar electric type) It gently shapes a baby's soft nails, making it recommended for those who are not good at using nail clippers. It comes with attachments for different purposes, allowing you to use them according to your baby's growth. You can also use it for adult nail care. Operation has been confirmed and it works without any problems. While there are signs of use and minor scratches, it's still in a condition where it can be used. It's also recommended as a trial item. *Please purchase only if you understand the condition of the used item. It will be shipped in simple packaging.
