The plastic-covered metal orthosis hugs the palm for a comfortable fit. No thumb pinch is required. Simply bend to make minor adjustments. Can be used with thin ballpoint pens and pencils. For additional wrist support when writing, use the Wanchik's Writer(R) #2. The plastic-covered metal orthosis extends over the wrist and up the forearm for added support and control. Attaches with D-rings and Velcro(R) closures. Both orthoses wrap around the palm with the opening on the ulnar side. Easy to don and doff.
