Washable Brush Tip Markers take coloring to the next level with a soft brush that’s just like painting. Create thick or fine lines depending on how much pressure you apply as you color or write. Twelve classic bright colors are great for drawing and hand lettering. Thickest part of the nylon brush tip is 4 mm wide. Not for children under 3 years of age. Care: Markers wash from skin most washable clothing and most painted walls. Wash promptly in a hot wash cycle. Do not use a pre-treat product or chlorine bleach. Repeat laundering may be required. Keep away from wallpaper unfinished wood vinyl carpeting and other materials that cannot be laundered.
