Let icons represent a (number) variable

I made a punch-ticket (klippkort) setup for a Swedish boat wash last week.
Simple prepay functionality etc etc.
After payment, a Blippa object is created, and a variable with the purchased number of boat washes is set.
And when the boat is performed, the staff scans the object’s QR code and deducts one wash.
Simple and straightforward.
But I wanted to show the remaining number of boat washes om the object page.
So, we enhanced the current “Rating” function to display the value of a selected variable.
And what icon and colour to show.
In this case, I choose sailboats as the icon.

(I also included the object token to make the object page look a bit more official)
