Peng is our in-house artist and he does some amazing work with hydro painting. Each of our Swirl Paint Tregleri beads is hand painted. These Tregleri beads are a solid steel bead with a powder coating finish. Peng does his magic with acrylic based paint then the beads are coated in a clear gloss acrylic to make the colors shine and add a layer of protection. Each one is a unique piece of art. Note: All paints and coatings can chip, but these beads can take their share of abuse.
