Poured resin painting, created with mica powder, resin and real shells! This is a lengthy process and amount to 5 pours, with 24 hours between each to solidify. 13.5 x 16.5 inch includes frame. This one has a hand painted turtle on the glass and sealed with a clear coat of resin. These are made to sit in a window as when the light comes through, it lights up the waves! They can go on a wall, but are heavy so need extra support. They are resin'd into the frame. The shells are real and came from all over the world.
