If you are willing to go that far why not just go there yourself? You can either mail it back to yourself or check out the custom laws and bring some back with you. Hell, call customs and be straight with them and see it it is illegal or what the proper protocol is. Maybe leave out the part about the dolls appearing underage, (that even sounds stupid, dolls don't fall under any age of consent law, it is the obscenity law to worry about....which even sounds more stupid).
In my later posts I was talking more about the smaller "Onaholes" they have, packaged in boxes depicting lolicon imagery, and words describing the content comparable to a "Flat chested preteen girl".
Trust me, if I had the money to travel to Japan AND purchase silicone dolls, I wouldn't be living in this shit hole, driving my piece of junk car, and I'd do it in a heart beat. I would also contribute to the purchase of titles on this site a lot. That or just buy up a company like Web-Pulp and offer deep ass discounts for Akiba-Online members.
(note: the above is intended to be sarcastic/humorous. No offense intended at all, but my emoticons don't work most of the time so I can't use them to express that. My browser security settings are way too high, but I'd rather not fix it and risk what happened before with rogue ads giving my PC an STD.)
