Here are 2 short rulers, each only only about 12 centimeters long. (So, for small projects or to go in your pencil-case) They're transparent with one blue-ish hued & the other somewhat greenish. The interesting thing is that they look like they're a bit mixed up. The logo, in red, looks modern...but the Sonic graphic is clearly classic. One has standing finger-waving, the other has getting ready to run Sonic. All the copyrights are there, & they were made in Japan...but they usually don't mix up the styles so what's going on?
