| dried out rubber parts
Does anyone know why rubber parts dry out? I ask this not because it happens to me but rather that it has not. Well at least my magic fingers and cup seals are both still originals.
I live in Canada where we do not have intense heat all year round. My marker has lived half of it's life with and half without humidity too. It has also lived in one basement or another as well. I know that sunlight will kill rubber but what else does it? Why have your magic fingers died?
