Apparently it's a normal black magic wand with white tips... in reality it's a versatile tool with which you can make little magical gags. In the hands of the magician, in fact, the wand will become very small, or it can appear as a tiny elf's wand and then transform it into a normal magician's wand.
Impossible not to have it!
Easy to do and fun to see. The wand reaches a maximum length of 20.5 cm.
