Don't waste your money! The only thing I could see when I looked through every one in the packet, was a blur. I threw them out. The Mini Prism Scopes were better.
DO NOT BUY! I would give these ZERO stars if that option were available. I looked through every one in the pack and the view was the same - fuzzy blur. I threw them away. I had also bought the "Mini Prism Scopes" and kept them - clearer, not frustrating for kids. Just don't expect super clear kaleidoscope. But...DON'T BUY THESE ONES!
