If you own a cartridge/converter pen, then I don't have to tell you that one of the most tedious tasks is cleaning it out. You're sitting there, twisting and untwisting that stupid little converter over, and over, and over, and over….it's enough to drive you nuts. Well, there is an easier way!! Get yourself a bulb syringe and flush that bad boy out, just like I do in the video. It'll cut your cleaning time way down, and bring your enjoyment level way up!!
