The SpaceSaver is a convenient system for making smaller pots and maximizing table space in your studio. The entire system is fully compatible with the now unavailable Wonderbat. It consists of a 14" adapter bat and 8- 6" insert bats. Both are made from a 1/2" exterior grade MDF which provides excellent bottom drying and rigidity. The adapter bat mounts on standard wheel-head pins with rubber "through hole" grommets making a true two-sided bat.
