Walking Nijmegen Four Days Marches is quite an achievement. That deserves a flower and no ordinary but a gladiolus. A whole bunch full. The distance is shown on the shield.
This pewter pin with color print is a nice reminder of a fantastic performance. Get it for yourself or buy it as a gift for someone who deserves it.
The color on the flowers is equal to that of the route.
30 km = blue
40 km = yellow
50 km = red
