123x64x57mm laser controller power supply LC-3 / 40-03Bird bath are mostly made of porcelain, because apart from pecking at rice, bird bath are more convenient for birds to drink, so porcelain bird bath are the most suitable materials for all. Because the ceramic is heavy, it is not easy for birds to turn over when they step on it. It is better to find wide than high.
