Review on Ceramic 🛡️ Reusable Contamination Shield by Adam Quintana

There are a few small ones but they fit my small size well. The material seems fine, but I'm not sure; The sellers of the product claim that it is made of eco-friendly material, no health and safety, no lead, etc., and that's why I bought it. However, this is not confirmed on the product itself or on the product packaging. There are no labels or stickers on the product or packaging that refer to these "Specifications". Why should I believe them? The consumer cannot know that this product is what it claims to be!
