Review (2/5): $1.49 in stores!  Impossible to paint with!
The concept of these is great, but I don't recommend them for 2 reasons. First, they are so liquidy, it's impossible to "paint" anything with them! They are the same consistency as your average conditioner, and they don't stay on the side of the bath wall as kids try to draw with it. It ends up dripping right into the water. The second problem I have with these is the price. Amazon is usually pretty dang good with offering the best prices around. I paid just over $19 for the 6-pack of these, which I assumed was a reasonable price. That is until I found them for $1.49 at Walmart and $1.99 at Kroeger. It's pretty bad that these are over 50% more expensive on Amazon than in the store. Terrible deal, and impossible to paint with. I would stay away from these.
