I don't know the official name, but it's a fun paddle trick. It's a plastic stick about 9.7 cm long with the numbers 6 and 15 written on it. It's 3-4 mm thick. In the paddle trick, it's shown as 6 and 9, and when added together, the answer is shown as 15. I found what appears to be an English instruction manual, so I'll include it.
