Speedball Speedy Carve Blocks (previously known as Speedy-Stamps) are available in 3 sizes
Flexible, durable and will not crack, crumble or break. These latex-free rubber blocks are easily carved using the Speedball Linozip Safety Cutter. Designs can be drawn directly onto the block or transferred from inkjet prints or newspapers. The rubber is so flexible it can be bent around curved objects for printing onto flower pots or jars, and dense enough to use for creating patterns on polymer clay or silver clay.
Use with water soluble block printing inks or thickened acrylic paints.
