Supermassive Black Hole Keychain
The darkness among the stars is a supermassive black hole at the core of a galaxy in a remote part of the universe, as imaged by the Hubble Space Telescope. The event horizon makes the light from background stars stretch and smear due to the massive gravity equal to 17 billion suns. Black holes are though to exist at the center of every galaxy.

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!
