The Speedball Linoleum Block comes mounted on 6x8" medium-density fibreboard (MDF) for convenience. The wood is very dense and strong and will not crack or peel.
The Speedball Fluid Cold Press Watercolour Block is made of high alpha cellulose paper and has the look, feel and performance of 100% cotton with archival quality.
The Speedball Fluid Hot Pressed Watercolour Block contains 15 white sheets of high-quality hot press paper with a subtle tooth that allows for a variety of watercolour techniques.
The Speedball Metal Flakes can be used on plastic, wood, glass, paper, metal, ceramic and plaster of Paris. Metal flakes give a completely different effect than traditional leaf sheets.
