Discs of handblown glass with open mouths at the center where the pieces are broken from the glass master’s pipe and flame polished, giving each a unique detail. SkLO Pool Wallpieces are hung with handmade steel wall hooks. The steel wall hooks come in two different depths, 3″ and 4″ (75 and 100mm) to allow for slight overlapping of the discs. Unless otherwise specified, a mix of 3″ and 4″ hooks is provided.
