Our Crayon Sharpener works for any sized stick crayon - even the wide Stockmar crayons. This is a great way to make those shavings for use in shading pictures! The wood top which holds the razor can be carefully taken off of the thick cardboard base to empty out the shavings. The crayon hole measures over 5/8" at the top. The cardboard base is 1 1/2" in diameter and 2" tall. Wood top and cardboard base fit securely together. Only for use by children over 5 with parent supervision. Made in Germany.
