- Most of the time the box is the same and if there is any change, the manufacturer will usually communicate about it.
Take for example ITEM #12, if you look at the details of the multiple releases it's had, you'll see that starting from 2014 Kotobukiya changed the package and rebranded it as "Renewal Package Version" and assigned a new barcode to reflect the change.
- It's usually the old box as far as I'm concerned. They usually already have the work of the blister and box design that they could just reuse. Plus, I don't really see why they would make a new one unless it was some special edition. :) It'd be interesting to see old nendoroids with new boxes though.
