International Transit Times

One more piece of information, I shipped it to Singapore via Fedex and it took 5 days.

It's probably on a ship somewhere in the Pacific.  Don't give up hope. My bet is you will eventually receive it, but "when" is the question.  Obviously, anything going from Singapore to NH, or anywhere else in the US, is going by air.  Obviously, your Koetsu isn't.  I wondered why you chose to do the rebuild with "Koetsu SE".  Koetsu, the parent company, is in Tokyo.  I imagine Koetsu SE is a distributor, only. In my experience, the parent company in Tokyo are very fastidious about service and ship by air. (I purchased an Urushi in Tokyo, from a bona fide Koetsu dealer who gave me a certificate in Japanese.  When I got back home to Bethesda, MD, I found that the cantilever was misaligned.  I sent it back to Tokyo, and they replaced the defective sample with a perfect one, no questions asked. The whole transaction took no more than a month.)

And let's not blame the USPS.  So far, the USPS has had nothing to do with shipping this cartridge and won't until it finally arrives at the OP's local post office, whence it would go out for delivery. USPS is too often unfairly the whipping boy.

I could not find contact information for Koetsu directly anywhere. Do you have that information lew?

thanks

Not at my fingertips. Plus, I think my return went through the dealer, in the Akihabara electronics mecca in Tokyo. They dealt with Koetsu on my behalf. If you really need their contact I’ll make an effort.

No need to search for it. I have worked with Mel Ang at Koetsu SE several times and it has worked out fine. I just don’t know why he used such a slow method for shipping.
