These are pretty cool! I have a lot of those stick-up dry erase decals on my fridge/cabinets/office wall for quick reminders so my kids always ask to write something on my "boards" to help out. My MIL got these crayons for my daughters - they LOVE them. They're easy to tell apart from regular crayons so there won't be any mishaps. We bought a separate dry erase easel so they could draw on a bigger surface. it's easy to wipe off - even if they forget to wipe, I just use some glass cleaner and it comes right off.

I gave this as a gift, I heard mixed reviews on it , one that they love the colors, but you do need a cloth to erase, or you get it on your hands. I think if you would like color or looking for fun on your board, then this is really good.
