This is an important advice for egg cup collectors and, in general, for people who'd like to keep some egg cups around for decorative porpuses: never leave too long a wooden egg in a glass egg cup. Wood may expand, glass surely won't, and the consequences could be terible. I have seen it with my own eyes. Having said this, why wouldn't everybody love glass egg cups? We do.
