I have been using Koh-I-Noor Woodless Colored Pencils for the pieces I do and I love them. I picked up my box at the Thrift Store for $1 about two years
ago and have been adding colors through Dick Blick on line.
I love the way these pencils "work" and how I can achieve a depth of color
easily with them.
These pencils have a laquer coating, and 5 times more lead than a regular
pencil. They come in boxes of 12 and 24 but you can also purchase just the colors that you want/need. AND...they can be sharpened in any regular pencil
