Pygmalion Numarkasten One set of 5 balls attached 19 individual balls Total: 24 Purchased 1.5 years ago, before the start of class. I didn't use them very much. The teacher quickly gave problems when the numbers were greater than 5, and I think the set of 5 balls is convenient. If you would like, I can include some of the teaching materials' printouts. Please check the condition in the images before purchasing. I plan to list other Pygmalion goods as well. The items will be packaged without bubble wrap.
