After a lot of searching, I found a Canadian company which manufactures the type of things which (I think) you're after. Following a link from their site, I've located their European wholesale distributor as Philos GmbH & Co. KG. I can't find any pricing information on their site but I suggest you check out the links, under Puzzle & Thinking Games, down the left-side of this page:
http://philos.quasarshop.de/ListWarengruppen.a sp?ID=DK&AG1=DK&Lang=E&Action=LWG
If those are the type of products you're looking for, you can use the contact page from that site or write to Philos GmbH & Co. KG, Friedrich-List-Str. 65, 33100, Paderborn, Germany.
