Organizing by color can help you find things and remember information. With these highlighters, it's easy to change the color, or remove the color completely - the opposite end of the markers feature a "magic" clear ink that erases the color! Highlight and erase without damaging books or documents. Chisel tips allow you to create thick or thin lines. 6 double-ended markers with vibrant colors: blue, green, orange, pink, purple and yellow. For ages 6 and up.
