Liquid Chalk Marker Seems To Be Drying Out

Sometimes, if the markers go unused for a while they need a little love to get going again. First, shake it vigorously for at least 30 seconds. You need to hear the ball bearing moving inside as you shake it. Keep shaking vigorously for at least 10 seconds after you hear this sound. Now prime the nib by fully pressing it down on a clean surface. Hold it down and/or pump gently until the ink comes out.
