7 Frixion Pen Holder

This is a remix of the Pilot Frixion Pen Holder (double sided, 8 pens) to be single-sided and hold 7 pens. The original case they came in has started to fall apart, but it fits really well in my backpack as one row of pens, so I wanted to copy that. They don't fall out easily even if turned upside down. The original was well-made!
