I guess I better hurry and get the recent buys in the store, so people will have something to look at. Most of the Murano weights sold in the last couple of weeks.
I've looked a bit more at generic millefiori PWs today. The canes of weights like mine look a lot like those that are used on the egg-shaped weights -- the ones that don't have patches of satin glass showing through. I guess for now they'll have to go into the generic category. Generic is definitely not bad, because it just means that no one seems to know who made them.
