Sustainability is considered when manufacturing the products. The products are packaged with environmentally friendly and recyclable materials. All products are sanded and sealed. So it's possible that there are a few air bubbles or bumps, I'll do my best! The products are waterproof and fireproof. The material consists of a combination of reactive mineral powder and water-based acrylic resin, making it environmentally friendly. It feels like stone but is lighter and looks very high-quality. It is best to wipe with a damp cloth and do not clean it under running water. The products are not dishwasher-safe. The material could chip or break if dropped.
