Fluorescent Pen Set of 6, ZEBRA OPTEX 1, etc.

This is a set of 6 fluorescent pens/markers, including ZEBRA OPTEX 1, in 4 colors.

I am selling these because I purchased them previously but haven't used them.
They have been used very little, so the tips are clean and there is plenty of ink remaining.

The original price is 80 yen per pen, so this set is priced lower than the original retail price.

ZEBRA OPTEX 1: Orange
                  Yellow
                  Green
                  Blue
Fluorescent Marker: Yellow
Fluorescent Pen: Orange

Thank you for looking.
