is there such thing as s pen combined with real pen?

A friend of mine said he has used one before but I cannot find anything online that references is it seems like this will be a very popular item or something people would want does anyone know if it exists?

I haven't seen any like that. I've seen passive stylii with a pen on the other end, but not an S-Pen.
