The Micador Mega Markers are the widest super washable markers! The pack as 10 bright and vibrant colour that children will love, with each marker having 7 grams of non-toxic, water-based ink that washes out easily in cold water. Dry markers can be re-hydrated easily by dipping the nib in water. The cone shape of the nib is great for both wide and fine lines and is designed to be sink proof. The chunky barrel will suit a child's full handed grip with a die cut ventilated safety lid and no end cap.
