Ring Stamping Device Accommodates standard stamps with approximately 5/16" square bodies. Eliminates the need to hold ring and stamp in one hand. Simply position ring over mar-proof plastic anvil and tap stamp with mallet. Easy and accurate time-saver. Eliminates slipping of ring. Also ideal for flat stamping. The sleeve can be reversed or the stamp body can be touched up with a file if stamp is not 5/16" square. Stamps must be ordered separately.
