Chalk pens are a great alternative to dry erase pens for our Circle & Square decor custom boards because they never stain, wipe off easily with a towel, and don't accidentally wipe off if your hand brushes over it like a dry erase pen would. Stay extra organized by using a different color for each child, task or chore. You can choose different marker sets: - Deluxe Pack includes all 16 colors: (Red, Orange, Yellow, Green, Blue, Purple, Pink, White, Bubblegum, Royal Blue, Peach, Deep Burgundy, Easter Yellow, Plum, Soft Orange, & Sea Green.) **PLEASE NOTE: I guarantee the board will wipe clean with my Circle & Square markers. I've tested endless types of pens throughout the years and we use our favorite! Not all dry-erase markers and chalk pens are created equal and some don't wipe clean on whiteboard surfaces. Because there are so many different brands, quality levels, and types of markers out there - I cannot guarantee someone else's product will work flawlessly on my boards. However, Circle & Square markers are of course always guaranteed**
