If you are interested in DAKIMAKURA type pillows used in this type of activity, take a look at the dakimakura thread in the 4chan archive. It covers where to get them cheaper, care, and various other things that can be done with them. There's a lot of detail in that thread. It even talks about the bootlegs that
J-list.com used to sell before someone caught peter payne (jlist owner) at it. So just because someone claims it is authentic and licensed doesn't mean it is and you should not have to pay an inflated scam price like what jlist charged.
