Chachacha brown is the 6th model kit from the Petit'GGuy series. From previous Petit models, the name has always been related to an adjective. So we're not sure where the Chachacha name came from. It would have been better if the name was Choco Brown instead.
Inside the box are a combination of light and dark brown runners. We're excited on building this model and have it displayed with Milky White.
