Ichiban Kuji Godzilla Prize E Head Magnet Anguirus Rare Item

Brand new, unopened!
Upon closer inspection, I noticed a slight difference from the commercially available product... It's believed to be an error item (a product that shouldn't have been released).
I've included comparison photos (the one below is the error item).
The characteristic is that the pupil of the right eye is round, not semi-circular.
*I've circled it with Akamaru. I've also circled the genuine product for comparison.
