R,

I asked few of my friends about the silver ball,
none of them can do it,
I even ask some friends who used to make jewelrys, and seems like it's quite diffecult to make.
but I asked one hand made jewlry shop near by my office today,she said she can custom one, but it cost 2200 N.T.though :(
I don't know if you really need that thing to make you feel more secure.or the crystal is enough for you.but I do think you will win the lawsuit,coz you did all the hard works and you have the contract.
the bad people always get punish at the end,that is the movie always played about.so don't worry,you will win without the ball:)
also I'll share my good luck for you.
so don't give urself too much stress ok?

best wishes

Ar
