I just placed my order for the windy ring, keychain and a baby choco
Ring sizes are in Japanese standard sizes, need to view item to get the US ring size estimates. There weren't any EU/England size estimates listed unfortunately,
I ordered mine without viewing it first, but I got lucky and ended up with the right size anyway
I suddenly have this suspicion that the baby choco plushies are part of the Taru World Domination Master Plan...oh well, as long as I get the cuteness Shantotto can own the world. 
those rings are $99
