Here are 2 wallets by Bio World. They both have the same theme, but are in different formats. To the left is the usual tri-fold faux-leather type wallet with chain & strap that Bioworld makes in loads of Sonic styles. It has Sonic on one side & Tails on the other. The background is the modern Sonic logo in English & Japanese. The interior has the snaps, usual 3 pockets & ID window area. The flat wallet has Sonic & Tails in the same poses, with the same scattering of logos, but adds a yellow starburst as part of the design. Now you can have a Sonic & Tails wallet no-matter which style you prefer.
