Found this on UK eBay. Clear acrylic tubes filled with unfoiled rhinestones from 1PP to SS29 in the Siam and multicolor tubes, and 27PP in the Crystal tube.
Tubes are just over 3" long. The caps and funnel appear to be silver plate as they do tarnish, but aren't stamped.
Might have been a store exclusive at Kristalwelten. Probably not more than 10-15 years old.
