nguyen thanh ha,
I am not Mr. Robert Wooding, but I am familiar with Schmalz &
Fischer. Although they may both, coincidentally, have locations in
Idar-Oberstein, I think you mean Pforzheim. I have not yet shopped
at Schmalz, and would need to confirm their address, but I believe it
is on Poststrasse. If you visit Pforzheim, a definite must for
jewlery makers visiting Germany, the Information Center will know
their address, as they are one of the big supply shops in town. I
do, however, often shop at Fischer. Their address is Berlinerstrasse
18.
Good luck & have fun in Germany!
