Precision sharpening for your Spectrum Noir Blendable Pencils; create the perfect point, cleanly and smoothly. Compact and easy to transport with your pencil collection so you\'ve always got it available for use. When sharpening, be sure to turn the pencil sharpener around the tip of the pencil to sharpen vs. turning the pencil around in the sharpener. You\'ll find that you waste less of the pencil during sharpening and the pencil lead is less prone to cracking or breaking when sharpened in this way. This Twin Pencil sharpener is for use with Spectrum Noir Professional Colouring Pencils, Colourblend and AquaBlend Age 14+
