Like any good flying piece of wood, this Broomstick is all one colour: brown. It makes no noise when in use, and takes a long time to build up any horizontal speed (though it has very swift vertical movement). Riders who mount a Broomstick sit side-saddle (male and female both), rather than astride the stick.
While being ridden, glowing yellow stars of various sizes will emit from the tail of the broom.
The Broomstick is a VTOL-style craft, it can hover in place or fly straight up or down. It is also a preferred vehicle for many Characters, so if you leave it somewhere, don't expect it to be there when you come back.
This is a very common item found in many sets, including the Harry Potter-themed Quidditch Match.
