Cute Set of 10 Liquid Chalk Markers for Painting on Windows, Chalkboards and Glass. Cool Cat Pens Draw Nicely on Ceramics, LED Boards, Steel and Other Non-porous Surfaces. Erasable Ink is Kid Safe. 8MM REVERSIBLE TIP: Our set of 10 artist-quality Chalk Markers with 8 grams of ink are different from the standard 5/6mm marker you see everywhere. You can write bigger, thicker, bolder lines and still be able to make thinner lines. Also, these tips will hold up better against rough surfaces- rough users like kids too! If you do damage the nib, you have the same exact profile on the other side, so just reverse it and carry on. COOL STORAGE CAN: You have found the most unique chalk marker set on the market with Cool Cat. This plastic bucket will fit right in to your Arts and Crafts room, college dorm room or with your home office supplies. There is so much space that you can store an additional 10-Pack of Cool Cat Chalk Markers in the same can. Or, if you must, your old 5/6mm markers can fit until they run out. Also, the lid is specially designed to be easily removed by hand- no screwdriver needed. CLEAR PLASTIC BODY: Yet another unique design feature you will only find with Cool Cat is the see-through marker and tip holder. When initially charging the paint pen, you can watch the ink flow down the nib, relieving the anxiety of wondering if the marker is going to work. Your nibs will thank you for this. These markers are great for parties like a slumber party, weddings and holiday celebrations. 10 EYE-POPPING COLORS: We thought hard about providing you a pair of sunglasses with these chalk markers because the colors are intensely bold and bright. You will love all the colors: red, orange, yellow, green, purple, blue, black, white and brown. Once you put these markers up against your dry-erase markers, you will see the vast difference. Your restaurant menu, baby shower signs, scrapbooking and contact paper surfaces will be massively improved. BEST ON NON-POROUS SURFACES  Like all chalk markers, Cool Cat Chalk 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
