If the shop won't answer whether the advertised discs are available, or whether they would ship something else, then how do you expect forum members to be able to answer that question?
the problem is if i get the wrong delivery to germany,
the cost of delivery are too expensive to send it back.
i'm only interested to buy verbatim pastel (taiyo yuden).
JVC CD-R are now also manufactured by Taiyo Yuden, and you should be able to get some from shops that are in or ship to Germany, such as Nierle or <s>DamroTech</s>. I haven't tested those JVC CD-R myself, but they are genuine Taiyo Yuden.
EDIT: DamroTech doesn't currently list any JVC media.
