Poppapia 5 I have never used this kind of paint crayons before! I was amazed by how it does not smudge or smear! Its so soft to use, even softer than a pastel crayon, yet it doesn't smudge, stain, or transfer to other pages!! I am truly impressed and so happy to have found this fantastic art supply for my kids! It is not used to draw details etc, but rather for larger background painting etc. The colors are bright and beautiful! I would recommend these to anyone whose kids love arts and crafts! my children absolutely LOVE using them! Great invention!
