Harry Potter’s wand was 11″ long, made of holly, and possessed a phoenix feather core. The phoenix who gave up his feather actually gave up two feathers for the making of a wand. The “brother,” according to Ollivander, belong to Thomas Riddle, who became self-described “Lord” Voldemort. The feather was donated by Fawkes, Dumbledore’s pet phoenix.
This wand is an “interactive” wand and can be used to make all sorts of magical things happen at Universal Studios in Orlando and Los Angeles. Here is the non-interactive, but still official, Harry Potter wand.
