About the company
Sadly, the Utrecht pencils have been discontinued.
Utrecht is an art supply manufacturer and store, that also sells over the internet. They are now owned by Dick Blick. They offer a store brand of colored pencils, which are made in Czechoslovakia, very likely by the Koh-I-Nor company. They are oil based, and blend well.
The Utrecht colored pencils come in sets of up to 72 pencils, and in open stock. They do not have a matching set of watersoluble pencils. The Dick Blick pencils and Koh-I-Nor pencils are the same according to Dick Blick. The exteriors are slightly different.
