I'm reviewing the Crayold tower of 150 crayons.  This is an excellent product.  My daughter loves to color and I was forever buying more and more crayons and she complained that she always had the same colors.  With this tower, there is nearly and unlimited supply of color and she can make all kinds of rainbow colors.  We have really enjoyed sharing time coloring pictures and making art projects with these crayons.  There is also a crayon sharpener that fits right in the tower, making it easy to keep track of.  the sharpener comes out to dump out the shavings, so I don't have to worry about...
