Simply Clean Solid. Powder Fresh Roll On. Funk Butter. In a world where deodorants' names are meant to bring things like bubble baths and ocean breezes to mind, Oyin Handmade's Funk Butter certainly stands out. It's not the most graceful of beauty-product monikers, but it's awesomely direct. And the product itself is pretty awesomely effective-especially when you take into account that it's entirely natural.
