Wood Pens Is It Possible To Use A Wood Burning Pen On Leather?

Is it possible to use a wood burning pen on leather? - wood pens

I have a number of children born of fire would give a friend as a gag. I think that might actually be able to use it, however, as they make their own leather handcuffs.
Can you use leather?
I know that to market, most practitioners and can be used in thick leather, but it is a work of children's toys?
Personal experience with this would be greatly appreciated.
Thank you in advance:)
