Don't throw 'em away! They are awesome dipped in water-kind of like water color painting, but with the control of the marker. They eventually will run out of "juice", but I promise your kids will love them!-It's even a fun outside drawing project-leave the mess outside! (y'know those kids usually end up tipping over their water cups!)
lol, I have to admit, I do this, and kids don't know they are drawing with dried out markers.lol and they last a little more like this. and of course at 99cents, why not.lol
