This is a Sonic X themed metal pen or pencil case. It's oval shaped, and likely hinged at the back. You can see it has a clasp in the front, or some kind of latch. The front and back feature some nice Sonic X art of Sonic & Tails, and the logo is a big feature on both sides. You can see the copyright very small under the logo, in the top shot. This is a nice and sturdy case, if you can find it to collect it. Likely released in 2010.
