works great! you do have to put a battery in it! Just an fyi

Gentle on baby’s nails and works very well! I recommend this nail filer set.

This product is what you really need for your baby's fingernails, I highly recommend it, it fulfills its function and what I like the most is that it brings the recommendation of how and at what time you should use each file, excellent
