V-grade labels designed for Boulderz Climbing Centre, a Toronto climbing gym.  The label set designates the difficulty rating (or V-grade) of set bouldering routes, and is colour-coded for ease of recognition.  A blank black sticker was included for route setters to write in V-grades beyond V6.

 

The stickers are used throughout the bouldering area, in order for climbers to easily discern

which climbs they'd like to try before getting on the wall.
