Manufactured from a blue, eraser-like material, Speedball's Speedy-Cut Easy™ Blocks make for easier carving than traditional linoleum blocks and are great for printmakers of beginner to intermediate skill levels.  These blocks are durable, resisting flaking, cracking and crumbling. Available in four sizes, Speedball’s Speedy-Cut Easy Blocks are suitable for use with water-soluble printing inks only.
