This bangle was designed as a handy reminder to spellcasters of a more natural bent to use that handy spell. For non-spell casters, it's asubtly different bangle with a natural, organic appearance from irregular beating. There is a slight "wobble" to the edges when viewed from the side which is pleasingly different.
This bangle has a diameter of 7cm (2 3/4"). The designed surface is 2mm thick.
