eBay user kenisatitagain is selling lots of 25 German handmade marbles for usually $20 per lot. (One of them is $16) Most of them are clays, (undyed, dyed, foil, and Bennington). In several of the lots though there's a German glass swirl marble, and one of them has an old genuine agate! I already bought one lot, hurry before the rest sell out!

Pete, maybe this will be a way to get more of those German glass marbles to sell on the site! I'm sure the people on the wait lists will be happy!
