Like The Primal Cuff , very rounded at the top and flattened at the ends , but in a slimmer scale  , this unassuming little Cuff will slip onto your arm and probably never come off  .

3/16” / 4.5mm widening to 1/4” / 7mm.

For this very reason, a few companions would be a good idea ...

Lastly shown with the Primal as a counterpoint.

Will fit small and medium wrists.
