Black bootmakers wax

I an having trouble finding some boot-makers hard wax
Anybody know of any sellers offering this product?
I'd steal my fathers but his ball is down to the size of a peanut after 50 years of use
I need to wax some unbonded nylon thread for hand sewing and normal dressmakers beeswax is far too soft
