I have been using a stick of vintage Erasmic tallow,and sadly,it is a very underperforming soap for me.The lather seems to gather fairly well,but it really dissipates rapidly.There is little to no protection with this formula.It is the same formula as the tallow stick that followed this one in the black box .The formula for the Erasmic Supreme stick is the same as the current tub,and both are 75 grams and non tallow.The Supreme produces rich ,thick abundant lather,as does the tub.The red box tallow stick was produced by Amber House ,the current Erasmic is a Keystone product.
