Ask-a-Zebra has Ehlers Danlos Syndrome (EDS), which makes her joints and muscles prone to painful dislocation.
In a great post, she documents her experience with Silver Ring Splints, custom-made jewelry that stabilizes her hand and helps her write and type — while looking absolutely awesome.

So cool! Beautiful to look at and has such a great purpose!
