How do I best store my Copic markers?

Please store your Copic markers in a cool place which is not exposed to direct sunlight. Direct exposure to sunlight or strong UV rays may cause the body of the marker to crack and the color of the ink to fade. To prevent the ink from accumulating on one side, we recommend storing Copic markers and Multiliners horizontally (however, even if the ink accumulates on one side, you would be able to use the marker/Multiliner again after putting it on the other side and waiting for a while). Also, since our ink is flammable, please store Copic Ink (Various Ink) in a place out of reach of fire.
