From Duke Cannon here is their Big Ass Lump Of Coal soap. 

This is one bar of Big Ass Lump of Coal Duke Cannon Men's Soap, 10oz. Perfect gift for your favorite guy.

Of this soap Duke Cannon says " Legend has it St. Nick used to reward misbehaving children with bundles of twigs, bags of salt, and strings of garlic. Considering these alternatives, a lump of fossil fuel doesn't sound half bad. Duke Cannon honors this tradition with his Big Ass Lump of Coal - a premium soap formulated with activated charcoal and featuring the masculine scent of bergamot and black pepper. "

At 10 ounces our soap bar is 3x bigger than most feminine soaps. Steel cut grains for max gripability and manly exfoliation.
