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 set of six Brush and Super-Fine Nibs has been designed to be used specifically with the Spectrum Noir Illustrator Pens, so pair them up and get the most out of your collections. All my items come from a smoke free home and will arrive well packaged by first class post. I will combine post.
