Awesome Awesome Awesome!!!!

I ordered these spinners because they were stainless steel and not aluminum so they shouldn't rust. They are so easy to do and the prints are so beautiful. You can customize them with a dog or cat that passed. They are so bright and shiny. They do have a hole on the bottom to add a bead. You also have to take the plastic off the front and back. Easy to bend and a lot of people like to dress up there windows or yard. I bought them many times because they never disappoint.
