I knew they weren’t metal. They are plasticized material. They are bright, festive and good-sized, but I wish the stakes were longer. Not hard to attach. I will spray overall with a clear protective spray. They come flat and you punch them out. No biggie. Overall I like and hope they last more than one season. They will be in front of shrubbery, hoping they don’t blow over. Update This is how I used them out front.
