I found them at Animate when I went to buy comic book covers. (I put covers on the all the tankobons I translate, so the dust cover stays in place while the book is tucked on my bookrest.)
A box cost almost 900 yen(!), so I just got three. I hit the jackpot with the first box: the secret version, Ciel dressed up as a young lady for a ball. (He’s even wearing drawers underneath his dress.)
I then got the devil and the shinigami butler pair.
The figures are very very detailed, compared to your average gashapon figures.
