Obviously a game has done under adult supervision reminding safety rules: it remains metallic nails! No problems with my 3 year old son who loves 1/2 make drawings and tap with a hammer to secure the forms. He never hurt or put in the mouth and neck are even fewer swallowed. So depending on your availability See before leaving this game and are planning to have children under the eyes but for their great pleasure to let their creativity! A bit small box, I was expecting a bigger board, but it seems to satisfy my spitz.
