Each round full-sized stick has a transparent label imprinted with color name and number, number suffix indicating whether it is a pure tone (.5), a shade (.3), or a tint (.7, .8, .9), and lightfastness rating. Light fastness is especially important when using pastels, since they're practically pure pigment and very susceptible to light. About 70% of the Rembrandt Pastel line has the highest possible degree of lightfastness.
Rembrandt Pastel Sets come in cardboard boxed sets with molded protective foam inserts.
