The Koh-i-noor Mondeluz Watercolor Pencils are advertised as having highly concentrated pigments in combination with the use of high-quality kaolin white clay for the core. This results in good, deep color and great application abilities. The thick 3.8mm diameter core allows for very dominant strokes that can cover great areas while still being able to retain the ability to do intricate areas. Overall these do quite well in all of these areas. The sets come in 12 to 36 pieces and have a hexagonal wood shell. I use watercolors mostly when i go outside to do sketching. They are easy to carry, it is enough to have only a sketchbook and pencils with you.
