About This Design
Optical Illusion Keychain
Instructions: 1) focus gaze on red dot 2) wait for disk to hover and wiggle over the background design 3) be amazed! (it helps if you clicky on the magnifying glass button there to view the product full-size). We're guessing the effect results from the differing characteristic spatial frequencies of the foreground and background that generate error signals during micro-saccades that the brain cannot cancel simultaneously. Science!

Premium Round, Large (2.125")
These are a durable metal and the colors are vibrant. One of the clasp came broken but received a new one quickly. Customer service was responsive and quick to resolve the issue. They are bigger than I thought but still work for my wedding. I am satisfied with the print quality and surprised at how vibrant the colors are.
