The moss ball grows very slowly. . . about 1 cm per year. It can be removed from the aquarium any time by emptying the water out of the pen, hold the pen upside down so the ball lies over the opening and remove it with your fingers or tweezers. It can be reshaped by rolling it around with your fingertips or in the palm of your hands.
The ink cartridge of the pen can be replaced any time with a standard ballpoint pen insert
