All my life people have told me to put the cap back on the marker or the tip will dry out. Sharpie being the world's No.1 black marker maker - has come out with a retractible tip version of their famous replaceable cap version. Now, I'm not so sure I'm willing to take the plunge and move up to the convenience of a retractible tip; at least not until consulting the highly valued opinions of my oil buddies first. So what ye say'eth y'all ? Is it safe to use these new retractible tip Sharpies without worrying about the tips drying out ?
