This 6" Fully UV Fumed and Sculpted Underwater Aquatic Rig features a removable 10mm 45 Degree 2-hole Difused Downstem. The Silver Fuming adds to the realism of making the one of a kind scuplted creatures look like they're really underwater. If you think the glass is shining it's definitely cause of the dichroic pieces going throughout the rig itself.
