Here are 3 uncommon bags!
These are part of the "Heroes Pack", a specific set of limited-edition bonus items for Sonic Heroes Japan release. There's a large dark blue tote bag with Sonic, smaller red bag with Kunckles & pencil pouch (cylender bag) with zip to that has Tails on it. Each character is a white sihlouette made from a CG pose.
What's the pose? The same one they use as CG art for the Heroes Pack 3 pin-button set. (On Japan Pins here at Gear). So, this merchandise matches. Because they were limited-quantity & only released with the game, this set of bags is quite uncommon.
