I cannot rave about this box enough! my boys really love this box!! the crayons are made of such amazing quality. The themes and crayons are so fun! I have 3 boys and 1 box was enough to keep them all occupied! it's been so fun watching my boys get so excited when this box comes! I love the letter ones too because it's been helping my boys with letter recognition! You will not be sorry with this box! my boys are aged 3,4,4 !
