These 2 great items were likely found together. The left is a soft pencil/pen case with Sonic X theme & the right is a zip binder or note-book holder with Sonic & Shadow theme. Notice the clever zipper pull is a puffy chaos emerald! What a great touch for these items! The same company made both, as evidenced by the identical tags.

These were probably both released some time in 2010. But where could they be bought at retail? The set obviously had a lot of thought put into it, and is nice to collect.
