It isn't often that a new pushbutton comes out to the market that is drastic in it's shape.  Unveiled at the Tokyo Game Show 2012, Sanwa released it's "Q" series button, which is a more emphasized convex button (see pictures).  Sanwa made some prototypes which were given to us at the show and when officially released, they decided to release them with solid colored rims and clear white plungers.

We asked them to take it a step further and make a custom run of solid rims, with matching clear colored plungers, like what you see in their clear series OBSC30.
