While they manufacture in the USA, which provides some labor protection assurances, they lack clear environmental policies and public ESG commitments. Their packaging uses some recyclable materials, but they don't have published goals for reducing environmental impact. The company provides minimal information about their supply chain and component sourcing practices.
