The Van Dyke urethane rock bases are ideal for life-size mounts. The urethane rocks are created from a semi-flexible urethane, reinforced with wood making them strong yet very light. The larger urethane rocks are reinforced with fiberglass and some have wood embedded for acceptance of casters. (Measurements are in inches).
• Reinforced with wood to make them strong yet light!
• Lighter weight means less shipping damage!
• Great for hanging on walls!
