It's really cool, isn't it!! However, since it's a Gashapon, you might end up with duplicates or not get all the parts you want. And it's expensive!! I'm on an allowance, so I can't keep drawing until I get the complete set of casing and contents.
And I ended up with two Unicorn internal mechanisms, one regular wing, and one clear wing.
So I decided to attach the wing casing to the Unicorn internal mechanism.
I cut it up and sanded it down. The rest is down to the power of superglue. I never thought that my first modification of the new year would be this one, lol
