How can I find a dealer of those clay bird water warbler whistles? I’d like to buy a whole lot.?

There was a man selling them on the street in Krakow and they were so fun. My kids want to sell them this summer. They are little and you put water in them and they sing. So cool. Bird Water Wablers. I find them on ebay, but they’re expensive and are only singly sold. thanks!
