IDEAL ALTERNATIVE TO TRADITIONAL CHALK: The chalk pens are easy and stress-free for creating beautiful drawings and calligraphy in a playful way. The chalk markers provide the opportunity to capture and convey ideas and messages - how, when and where you want it, because every thought is worth writing down. FINE TIP: whiteboard markers with round nibs for line widths of 2 - 5 mm offer maximum marking performance and the tips write comfortably softly, without annoying squeaking. To ensure a longer period of use, please wear the cap when marker is not in use. MANY PURPOSES: Write wherever you want; on windows, boards and surfaces made of glass, metal or ceramics, especially decorations or gifts for the coming holiday. Perfect for bistro or restaurant menu board, business presentation in the office, blackboard labels or stickers for organizing your kitchen mason jars and containers, property for sale signs, car windows for dealership, erasable LED writing board on the cafe. EASY TO WIPE: Remove the paint easily and residue-free from non-porous surfaces with a dry or damp cloth. The paint adheres permanently to all porous surfaces (e.g. wood, paper, slate, etc.). To avoid contamination, always test the pens on a small, invisible area of the surface to be written on. SCOPE OF DELIVERY: Set of 12 markers, color: black. Before using for the first time, shake the pen vigorously with the cap closed for about 10 seconds. Then remove the cap and press the tip of the chalk pen several times for about 10 seconds each time on a flat surface. Pump until the tip is completely filled with paint. Color: black Water-based ink: just wipe dry or wet Packaging: Whiteboard marker black (12-pack) Tips for you: Not suitable for blackboard chalkboard. Please RE-CAP after use so that the ink does not dry out. Keep the board markers flat for the best results when writing
