Kalos Wax has the coolest design on the can of all the waxes we sell, in my opinion. Last week the Kalos Azulene Wax was the most popular, however, the Kalos Natural Pine Rosin came in a close second. Here at the warehouse we call them the "Blue" and the "Brown".. why? I have no idea... I'm just a shipping guy! See our great Kalos Wax selection HERE!
