solid, heavy, unusual and very versatile - looks perfect knotted on our leather chains and even cool on any silver or snake chain - also nice on bags , key rings etc..., pretty reassuringly heavy at 9.3 g, 3cm long and 1.5 cm wide, thickness of metal 3mm, size of cut out 1.2 cm x 5 mm, will therefore fit any chain up to 5 mm in diameter - nice!
