I was asked to add cufflinks and tie bars to my windsurfing jewellery range and here they are:
and small pendants
Lao shi loves the 20 000 km achievement badge I made for him (see his avatar on GPSTC website) and suggested others might like GPS achievement badges: 30 knot club, 10 000 km etc. They could be made in the style of the tie bar if you prefer. Let me know if you are interested.
