The Classic Oink Ink Mini Mop EMPTY is back! The finest mini mop on the market, from the original website for this perfect open flow mop marker. The classic cotton nib you can only get from OinkArt, easy to squeeze white plastic body, screw on top - ready to rock! Fill with the New Oink Ink or your preferred ink or easy flow mop paint. We do suggest keeping this mop marker in a plastic bag when in your pocket out and about as pressure applied to the body can force ink to flow out. Go out, have fun and ENJOY!
