Quartet EnduraGlide dry-erase markers have liquid ink to deliver constant colour and smooth, transparent lines. The patented, 3 chamber design ensures that ink is constantly brought to the marker tip. These explicit EnduraGlide markers have a perfect fine tip size which is excellent to be used on dry-erase calendar and planner boards with smaller writing areas. EnduraGlide markers are non-poisonous and occasional odor. The ink dries rapid and erases blank. Every marker barrel includes a see-thru ink gauge so you’ll be able to at all times tell how so much ink you’ve got left, so there’s 0 guesswork concerned whilst deciding if you wish to have to switch it. Roll-resistant cap helps to keep the markers in place. 4 % contains black, red, blue and inexperienced markers.
