So it starts small and chunky (3-1/2" tall), then push the button and the cover flips open (5-3/4" tall), in space-age way. Push down from the top to close. It's from Japan and they call it a frog pen. It's matte silver plastic (with black ballpoint) and has a retro look and design. Kind of like a transformer from the 1950s. Comes in a small box that we added a label that says “Robot Pen” in Japanese (at least we hope that's what it says--we put our faith in a free online translator so it could says “I robbed this pen” but we hope and think it's correct).
