Create visually appealing presentations, where each line leaps out in bold, vivid color. Feel free to fill your board without a worry; every mark you make erases easily from all dry-erase surfaces: glass, ceramic and melamine. With the tip type and ink color clearly indicated along each barrel's length, you'll never second guess which marker you've chosen. Unique Squircle™ barrel shape -- not quite square, not quite round -- helps you get a comfortable grip while minimizing the marker's ability to roll. Low-odor, non-toxic ink is ideal for whiteboards in your classroom, your conference room and your home.
