Sponge degrees are shown as published by Cornilleau and are never relabelled Shore A, Shore C or ESN. Max is Cornilleau's label for maximum legal sponge thickness. It is not OX, it is not a sponge-free sheet, and no invented millimetre value is stored for it. No reliable official Cornilleau list price is published per region, so no price is shown rather than an invented one.
