About This Design
Schrödinger's cat key ring
Schrödinger's cat is a thought experiment. The thought experiment presents a cat that might be alive or dead, depending on an earlier random event and, until observed, the cat exists as both dead and alive simultaneously. The thought experiment illustrates the bizarreness of quantum mechanics and the mathematics necessary to describe quantum states.

Beyond expectations. Choice of artwork is overwhelming, I found exactly what I needed from SJW_Graphics. Detail, colors, overall design looks great on this keyring. Could use as a pendant, purse charm, bookmark, too! Metal is sturdy without being heavy. Colors beautiful, with clear margins. Customized name makes this gift extra special. So many fonts, so many colors & sizes!
