Authentic No. 10 Post-Shave Cologne Balm at The Perfume Shoppe. Truefitt and Hill Authentic No. 10 Post-Shave Cologne Balm combines two great products in one! It has a nice clean fragrance along with the moisturizing properties of an aftershave balm. Contains Willow Bark, Borage Oil, and Tea Tree Oil to renew and refresh your skin. This works nicely on sensitive skin. Truefitt and Hill Authentic No. 10 Post-Shave Cologne Balm is a nice clean scent and is both a balm and a cologne.Very soothing and the scent is woody with a leathery touch...not too strong and lasts a long time. A unique and different application than other after shaves on the market. One doesn't need very much to do the job at hand which is both to feel and smell great! 1.7 fl. oz.
