There has been new designs created by Hot Toys for Spider-Man: No Way Home. This is the Battling Version (Movie Promo Edition), for a 1/6th Scale collection figure.

Rumours and leaks have previously called this a Cube or a Key. Now, Hot Toys have a codename called The Box. This item is displayed as playing an important plot device in the movie. In the trailers, Doctor Strange is seen in many disagreements with Peter Parker, and eventually chasing Spider-Man for The Box, through the mirror-dimension.
The Box is rumoured to be some form of prison key; for unlocking and keeping the villains away from the MCU.

The designs are still listed as ‘prototypes shown is not final, pending licensor approval’. Designs do change and it’s possible that he could end up wearing a differen suit in the movie.

The collectable figure appears to come with very detailed accessories: Webs, different lense, a wall piece, Peter’s mobile, the box and a wall set piece.
Spider-Man No Way Home is now three weeks away from cinema release.
