Tallow-based shaving soap—with lanolin, if you want
Prairie Creations is a vendor is new to me, but some guys over at DamnFineShave.com think highly of the product. I like how you get to choose (tallow or tallow+lanolin; scented, essential oils, or unscented; soap, cream, or shave stick). Take a look. She also sells aftershave balm, lip balm, exfoliating scrubs, etc.
