I asked Matt Miller of Hobie what their source was. he said they used a speciality house and bought them in quantities of 100,000.

I'm sure that Murray's would ship international. It would pay off to order a large quantity as they weight next to nothing and split them up among all your sailing friends. Murray's might even cut you a quantity discount.

Your might also contact Hobie Australia to see if they carry them and be open to selling small amounts.
