Uni Boxy 100 Ballpoint Pen - 0.7mm - Black Ink -with 3 Refills

First introduced in 1979, the Boxy 100 ballpoint pen has been a favorite choice for generations of Japanese students.

It features a unique flat-sided shape, a top push button that extends the tip and stays down when pressed, and a side push button that retracts the tip and releases the top push button. 

Not only does this design provide a unique and comfortable writing experience, it also lets you play a fun game! Japanese students would take racecar-shaped erasers and stage races and battles on their desks by lining the erasers up against the retracted top push buttons and then propelling them forward by pushing the pens' orange side buttons.

To refill the pen, use a thin object to press the orange side button all the way into the barrel, then pull out the top push button. Replace the refill, then reassemble the pen.
