Adapt and evolve your ideas with ease using EXPO Wet Erase Markers! These EXPO markers are permanent until you want it gone. The smudge-free ink stays put when dry, but with water-activated erasing technology they wipe clean with water! This variety pack features fine and ultra-fine tip markers. The ultra-fine tip markers are great for precision and clarity and perfect for adding details and embellishments to your calendar or marking on small spaces. Meanwhile, the fine tip markers make vibrant, sharp marks and are perfect for capturing plans that last, labeling with flair, or creating colorful displays.
