I've made these for Becky as the ones we had weren't right. Zam's hands should have a pointy middle finger bit, ours didn't and Becky felt they were way too large.
So I made these
And then I thought, well maybe you lot may want some too so I made these
They may need a 'little' bit of work to show up a nice groove etc, but it's not hard. Just file along the lines (if you want too) and then spray black. Then spray silver at a shallow angle (keeps the black paint showing in the groove)
you end up with something like this (first mould, it's since changed, and first attempt)
I don't know what to pass them on for ($ vs £ etc) so give me an idea if you're interested
