The original contract includes that they will produce and design the molds only if at least 500 sets will be produced (which will be the 500 transparent ones).
If we don't do that, they could blame us for breaching the contract and either charge more money OR (even worse) keep hold of the molds until that one production run happened.
Legally, they probably wouldn't get very far (with the delays they had), but a lawsuit could take ages (and hold up the molds even longer) and I'm not in the mood to sue them.
They are keen to fix the shoulder buttons first (they're too proud to admit defeat here I guess), so I
let them do it... if it works fine, then no more fix is needed and we can start to produce and if it doesn't, then we'll finally tweak them at the new company.
Pretty awkward situation, but a slow production is still better than a year-long lawsuit...
I've arrived at Fakuma exhibition now and will meet the CEO of the new company in a few minutes to check on modern plastic materials.
