Part of the Rilakkuma Panda Series, I believe this Rilakkuma panda plush set was only available if you pre-ordered it from the San-X Online Shop, after which it would no longer be obtainable (unless you were able to grab one of the cancelled orders).
This is quite a large set (25cm x 33cm x 20.5cm); Rilakkuma and Korilakkuma are almost as big as the regular sized plushes.
As limited editions go, the lemon cake bears from the Lemon Series is probably my favourite, but I also adore this. You get Rilakkuma, Korilakkuma dressed up in panda costumes, happily sharing a doughnut (sorry Kiiro!) and next to them is a treehouse, with a cute mini panda inside.
If you’re a Rilakkuma fan, I would recommend prioritising the limited edition sets with each release – the limited editions usually have better attention to detail and once they’re gone, they’re gone!
