My daughter is asking for 3D pen. I didn't find good reviewed pen. is it worth buying? any recommendations?

A. See you have to see what is the worth of it for the child like for what purpose is your child willing to use it and how long is your child going to use it because 3-D pens are not a very good option actually for a small child but still if your child wants and you feel it is fruitful to an extent then you can buy
