Used once. There are white spots due to lint and aging, but there is no difference in use due to the thick material. This is a square type of gold panning pan used for gold panning, a special order from Maverick for fossickers (although the only difference is the logo). The shape reduces wrist strain and provides high reliability (gold is less likely to spill). It only requires forward and backward strokes, making it ideal for beginners' first steps. (Search for "MAVERICK goldpan" etc. on YouTube to see how to use it.) I'm selling this because I have too many panning pans. I use the green one of a different color, but the blue one makes black and gold stand out more. It costs about $60-70 including shipping and customs from overseas, so it's a good deal for those who want to try the square type.
