Our nail trimmer is going to use you until your kid turns 10 years old
You will probably need to replace the file heads along the way
Our recommendation is to replace a file head every 3 month (depends on the frequency of use)
There for you have the option to purchase a separate file heads set
The orange file head set is the fourth stage and should be used when the thickness of the child nail is the highest, until age 10
It’s grit is with the highest grit level and it’s a roughest file head
