So P-Bandai just started orders for this year's Christmas items with Kyuranger and Kamen Rider Build themed cakes, this is also the only way you'll be able to get the Christmas themed Kyutama and Full Bottle:

Ha! That santa bottle is great! They don't usually have an entirely new sculpt for the xmas stuff, right? That may see some demand outside the usual completists.

Forget the bottle and Kyutama. I want the cake.
