These are made by punching out stainless steel sheets. Stainless steel is rust-resistant. Holes can be drilled relatively easily. They can be easily attached with double-sided tape, etc. These are magnetic. They can be used for children's crafts, reflective plates to deter animals, nameplates for tree planting, targets for air shooting (this is what I use them for most). Some items may have scratches from the punching process. Be careful when handling them as there may be burrs. Some may have oil on them from the manufacturing process.
