ZIG Wink of Stella Glitter Brush Marker Pen 030 Blue Colour: 030 Blue Nylon brush tip produces thick and thin lines allowing artistic freedom Archival quality: water based dye, odourless, xylene free To activate the pens, unscrew the lid and barrel , remove the black ring and then re-connect the two halves. Gently squeeze the barrel (where it says "PUSH") and you'll see the ink flowing into the tip, just below the brush. The ink will then flow into the brush and be ready to use. DO NOT OVER SQUEEZE, OR BLOBBING WILL OCCUR. Just very, very light squeezing is all that is needed. Add sparkle to your lettering or stamped brush projects!
