Chalk Pens for Chalkboard Art, Bistro Menu Boards, Wedding Decorations, Home Decor, Calligraphy, Windows and Glass. Set of 4 Paint Markers Has 3mm and 6mm Reversible Tips of Erasable White Liquid Cotton nib Imported 2 SETS OF CHALK PENS IN ONE: This art marker set comes with two different size markers- 6mm and 3mm markers. Both size markers have reversible tips for both bullet and chisel tip writing. The chisel tip will give you a fine and stylish line (like calligraphy), while the bullet tip will provide a more even line with less variations in the thickness. Plus, we provide a bonus chalkboard label for your Iced Markers box (so it doesnt go missing). EYE-POPPING WHITE INK: Cool Cat Iced Markers are filled with the most versatile ink around- bright, dust-free, non-toxic, odor-free, washable, erasable. This ink will give you the bold, professional, artists look you need. Just make sure you give the marker a good shake before use and periodically while using. CLEAR TIPS AND STYLISH DESIGN: Unlike sharpies and other markers, chalk markers need a bit of time to get the ink flowing. So, Cool Cat Iced Markers are designed with a clear plastic tip holder so you can see the ink flowing to the tip while charging them. You wont find this feature anywhere else. This will help keep you from pushing down too hard and damaging the nibs. If you damage the tips from too much excitement and energy, we have also provided 2 spare nibs. BEST ON NON-POROUS SURFACES  Like all chalk markers, Cool Cat Iced Markers erase best on non-porous surfaces. Examples are glass, windows, metals, ceramics etc. Our markers will look fantastic on porous surfaces, but they may not erase 100%. Certain type of blackboards and chalkboards are 100% erasable, others not as much. Try out a small section of your canvas before going all out. COUNTLESS USES  Try them on your wedding decorations, personal lockers, college dorm rooms, office dcor, holiday parties, personalized notecards, restaurant & bistro menu signs, car windows etc. Have a look at the product description below to see what else Cool Cat Iced Markers can do for you.
