This is the Soft Sides Sonic Tails & Knuckles lunch bag /box. It has all new (2011) and modern CG character art. Sonic is running, Knuckles is punching/gliding & Tails is pointing. With nice new poses & dynamic layout, the art here is good and fresh looking. The box likely has thermal lining to keep hot or cold food. It comes with the drink bottle you see at right, which appears to be black plastic. It also has Sonic Tails & Knuckles on it, with the modern logo. The dome cap protects the sipper part from dirt.
