Care per Martinis & Slippers:
"Our brooches don't like to be put through the wash. In fact, keep them away from water (and don't feed them after midnight). The surface of our brooches vary and can consist of acrylic, bamboo & hand cast resin & polymer clay. Some of the bamboo pieces are unsealed and therefore won't survive a trip through the washing machine. The acrylic pieces can over time get scratches on the surface. If stored correctly, this will not be a problem. Keep them out of direct sunlight."
