This is is a glass cup from Spencers Gifts, and it has quite a specific shape...is the shape meant for beer? (Different drinks have differently shaped things to drink them out of for whatever reason) It's sort of unusual to see matte finish black glass like this. Of course, you can put 10 oz of whatever you want in this tall cup.
Oddly, it's a mixed up item, with modern Sonic and 'after image' cascading line art on one side, but the classic logo on the other. It is 7.99 at Spencers in winter/spring 2013, which is an ok price for an actual glass item.
