This is a simple, bone-effect (moulded in white polyurethane plastic) keyring for fans of all things with a spinal column. Hand-made and finished. Anatomically correct, based on CT scan data.
These are TOUGH. Tested by my team of tradesmen who put keyring trinkets through hell.
It's not life sized (because that would be a bit too big), but roughly 35mm (1 1/8") square. Despite the vertebral processes, at this scale (about 1/4), it sits quite comfortably in the pocket (keys are more uncomfortable).
Unvarnished polyurethane plastic picks up grease and dirt after many months and begins to resemble aged bone.
Dispatched in an organza gift bag, to make an ideal present.
