These markers looked perfect for what I wanted them for, AND they were a great price as an add-on (which was why I didn't give one star). But they really disappoint once the lid comes off. The colors are bright and vibrant, but they bleed together. While they may wash off of clothes (I haven't had a need to check) it does not wash off of the dry erase board. Even after a few minutes, the black stained my dry erase board. No matter how hard I scrubbed, it's still there. I will try what someone else suggested, and use a clorox wipe. But, I don't like to use those, and I definitely don't want my kids using them. If I wanted a permanent marker, that's what I would have bought. These totally negate the purpose of a temporary writing surface. I will NOT be purchasing these again OR recommending them to friends.
Rubbish.
