creams look ok ,not dry at all to me too!!
i use most of the time(in the regular maintenance process) about 2ml per shoe(about the size of 2 pea )+ 2 ml of 1909 leather cream!! but always this is depending on the condition of the leather
the only reason i can think is marketing!! + selling les product at the same price 100ml Vs 75ml+ some product is getting wasted in the corners because you cant reach it so you bay more!!!
with witch brand? i heated one wax(completely melted) with a heat gun to make solvents evaporate so to use it easier for mirror shine and never had this problem!
W.S. Robson's shoe wax. Not sure if the solid gel spheres are wax or other ingredients, will post picture when I have time.
