Bruynzeel meets professional specifications in colour density and light resistance. It is a soft to semi-soft pastel producing a rich smooth application of colour that blends easily vs one that crumbles and creates a dust because it is too soft or one that scratches because it is too hard. The pigment is also soluble in this pastel.
As we know Pigment is everything, and pigment costs money, we aways have to compare apples to apples.
Like the old saying you get what you pay for...
