[Help Needed from people living in Japan] Phiten Necklace

I think these are from Japan. I need to look for a particular model. I guess they are readily available. Can the Japanese buddies help me take a look? Those at my place all are plain ones, not that appealing and of coz overpriced. If there is this for sale can you grab me one.. I will pay for it and shipping of coz.

It is the X50 Memorial Kanemoto Model im looking for.(50cm)

Thanks a lot.

Dennis.
