Six small circular grinding heads. Long main trimmer machine. One LED light on the front. Two batteries. Since babies' nails are soft, they often scratch themselves; this Nail Trimmer helps keep nails smooth and even. It includes six interchangeable grinding heads that can be used according to the baby's age. The power switch is on the top of the main unit to change modes. Once a grinding head wears out, you can use a new one to keep the baby's nails smooth. If you want to trim the baby's nails while they are sleeping, you can switch the trimmer to silent mode. It can also be used in the dark using the LED light.
