Are the stated width, height, and length the shipping size, or the size of the completed puzzle?
It’s the product dimensions.
Edit: Assembled size: 5.12” x 5.12” x 6.3”
Hmmm. You sure about that? My guess it’s the box it comes in. Or maybe that’s what you meant? See my second post below. The vendor’s dimensions / assembled size are very different. I think the YouTube video gives a better sense of it’s completed size.
