Tomica Disney Motor Tsum Tsum will be released in 25th of April 2015 for 800 Yen.
There are total of 8 in this series
Mickey, Marie and Donald are cars which is much smaller. Because of the top mini figure, I doubt it can stack anything on top.
For the Van which is bigger, you have 5 of those. Dumbo, Dasiy, Chip, Minnie and Winnie the Pooh.
Certainly interesting but if it is not that stackable, then it could have an issue. Because if it does, I am pretty sure some will buy more than 3 each to do the stack version.
So people who play Tsum Tsum are you waiting for these or your favorite had not release like me?
