The Millennium Falcon is a pretty versatile ship. It comes equipped with all manner of things to get you through a myriad of situations, but sometimes those things need fixing. The hyperdrive will eventually breakdown again, and you won't always have R2 there to fix it for you. You'll need some tools of your own!
The Star Wars Millennium Falcon Multi-Tool Kit comes equipped with four hex keys, two screwdrivers (one flat-head, one philipps), and an adjustable wrench built into the ship's helm. The hex keys store away nicely in the back underside of the ship which is sealed shut with the power of magnets. Screwdrivers tuck away in the sides, and the wrench is adjusted by a wheel located in the center of the Falcon.
