Address I used:
Hawaii Five-O
CBS Television Studios
Eye Production, Inc.
605 Kapiolani Blvd
Honolulu, HI 96813
Hawaii State, USA
It's totally correct address, I emailed with the CBS channel (the department, who deals with fans) and they gave me it.
I sent it in November 2013, approximately on 24th
I got it in February 2014, on 27th
The signatures got blurry due to my stupid postman, who put the letter not in the box, but simply left it, so it got wet a bit due to the snow.
