Spectrum watercolour pencils offer a good strength of pigmentation and when water is applied the colours create wonderful washes and watercolour effects. Generous 3mm cores encased in triangular-shaped linden wood barrels from sustainable sources. Comfortable to hold and even better to use. Great quality at fantastic prices make these a must for any art department. As these pencils can be used wet or dry, why not make them your everyday pencil for colour or watercolour work? Assorted colours.
