An unofficial seal of approval.
Dimensions (LxWxH): 24mm x 17mm x 13mm (approx.)
Weight per cufflink: approx. 10g (average)
(This is an awkward cufflink to measure accurately. The height from the sleeves (13mm) is measured as the widest point, which is the front legs. The rest of the seal is much thinner.)
