Sylvanian Families 30cm Cottontail Rabbits 30センチ シルバニアファミリー わたウサギ

These Cottontail Rabbits are 30cm tall.

Although they have the face of the Cottontails, they are actually wearing the clothes of the Grey Rabbit  (Babblebrook Family) mom and dad.

Aside from that, another notable difference is that instead of the green coveralls and blue checked shirt, the 30cm Cottontail dad is wearing his garb in brown.

These are the same rabbits from the Happy Cottontail Rabbits （ハッピーわたウサギ） 30cm figures set made for the 15th Anniversary.

I'm not entirely sure where these figures are from. I heard that they were promotional figures. 

If you have more information about these figures, please leave a comment below. Thank you!
