These are the colored pencils from Castle Art Supplies. They have soft cores, which Castle calls its Soft Series. The cores go on smoothly and are easy to layer and blend. They are made to resist breaking, and the round barrels are basswood.
There are 72-color and 120-color sets, each in a tin or a zip case. There are also 24-color sets with colors picked for a theme, such as landscapes or portraits.
In the 120-color set, each pencil has a number, which makes similar colors easier to tell apart.
