How do you fix a Fly Fusion Pen?

if you think your pen is broken check the spring to see if its not damaged. then look up to the top of the barrel to see if you have your shifter still there. the shifter lets you click and unclick your pen. after checking the basic if ink will not come out of the pen part. take you pen apart and CARFULLY blow into the pen to try and push ink out the other side. Do not suck in. if your pen still wont despense ink. then take the ink holder side of the pen and detatch it from you pen part check to see if anything is bllocking the entrance if so try and take it out. if not put it all back together and check to see if your tube is not broken or pintch. if pintched the ink could not get through. so take a smaller objecct like a tooth pic and try to slide it into the pinched spot to unpinch the tube.
