Design that gives you fun

This is very cool. Japanese design agency D-Bros has got something for us. We see here a set of really fun and creatively designed envelopes. They spring on lots of fun and also encompasses a rather unique identity for themselves. By pulling the tab you will unveil the graphic using the tearing off movement from your tab. We see the long trail of exhaust steam! This is definitely adding a little fun to our current state of technologically driven world.
