Country of manufacture not available. Technically it's illegal in the US, but the product itself is fine. So far I've only had to use the 45mm lens, but it's worked well and others are made the same way. Each comes in its own snap-lock plastic case. I like it, it helps not to lose the drill and quill. There is a small burp that I'm deducting a star for. The description says it can be used on iron, steel, stainless steel, aluminum and plastic, but the listing text includes wood, glass and ceramics. Okay not great but yes you can use them on wood. glass and ceramics? Ridiculous. I'm not an expert, just search amz and see what glass or ceramic crowns look like. If I disliked them that much for the Metal, I would deduct more than one star for such an absurd statement.
