Coleman Exponent camp mugs for camping kitchen, heavy stainless steel metal cups

Lot of two all stainless mugs, marked Coleman Exponent on the bottom. I don't know if these were originally part of a camp kitchen set or a stove kit, they seem to be hard to find these days!

They hold about 12 ounces, and measure 3 3/4" tall. Both are used, in good clean condition with just a few light marks and scratches.
