Has anyone seen these in the last few months?

I remember seeing the first one for sale for 300 mil when they were first introduced, and I've only seen the third one in a gachapon ad after you close MS.

But other than that, absolutely no sign of them o.O

The first one is the only one you usually see. That's because there are two versions of it I guess. I have never seen the 2nd or the 4th. Only in the gachapon adds when they were released.

Based on the lack of responses, I'm guessing the answer is no. And I really wanted the Smiling Mask too =(

I've seen the smiling mask. Never seen the other three.

Actually, you can probably find some via owl.
