3" Diameter x 3/4" Disks

These beautiful specimens were carefully irradiated and then discharged either in the interior or along an edge to create branching center or edge trees.  Edge has an attractive matte finish. Although the patterns may vary considerably from specimen to specimen, we guarantee your satisfaction with every one.  Also, see our newer Style 43 (3") and 44 (4") disks with a flat surface along the bottom edge. All interior discharges are at or near the center of the specimen. These specimens look nice with our BD985MC, CR35MC, ROT45MC or LM2690 light bases.
