I don’t know how long these have been on the market, but I just found them this evening and I think they are absolutely adorable! I love their simple design, and their clothes are darned cute too. Their only downfall is that they are $148 at Mimiwoo, and as adorable as all of the Petworks dolls are, they just seem a little too expensive from something made from plastic and without all the joints of a BJD or obitsu. Still though, I could foresee that if I had more disposable income I would probably be very tempted to buy the Petworks dolls. The January Nikki is a black and white cat in New Years Kimono that looks like my own cat too.
EDIT: OK, so I decided to hunt down the official Japanese Petworks site and they list the Usagii doll as costing 3,900 yen which is roughly $47 USD, so why the heck is the mark-up so dang high for these dolls? I mean really $148 is gouging. I think it’s time to see what can be found via Japanese hobby shops online. I just don’t understand it really, because Mimiwoo is fair on all other prices, especially Blythe.
EDIT2: Found a seller in Japan for a variety of dolly things. Usagii is sold out though, but it could prove to be a useful site in the future. http://biccoltd.ocnk.net/
