写真に3枚しか写ってないのは今日撮影したのですでに2枚使ってるからですねー。
両面基板で作るときにはこれからはこの業者さんを使おうと思います。
片面なら2週間待つのもめんどくさいし、自分で作れるので今まで通りに！
量産するなら頼みますけどねー。

The reason there's only three showing in the photo is that I took the photo today, and I'm already using two of the boards. I think I'll be using this supplier from now on when I make double-sided circuit boards. For single-sided boards, waiting two weeks is a pain, plus I can make them myself, so I'll keep on doing just as I've been! I'll place an order if I'm going to mass-produce them, though.
