Here's some old-school...school supplies. The big square is actually a metal tin of colored pencils produced by Tombo. It says "Segasonic" at the top, but features the Sonic R CG art. (Probably one of the last things to feature the 'segasonic' label)
Beside the pencil set are 3 erasers. The top is the "Sonic vs Metal Sonic" white eraser in glossy full color paper cover, the next has the logo...

but you can't really tell what else is going on because the photo is so small and old. The last eraser is different than the other 2, in that it is a shape eraser (without a paper cover) and it has the design printed directly onto it (running Sonic with his name below in red.
