ironmonger@replicaprops Here's one licensed by DC itself:
if you notice, the measurements are 5.04 * 1.26 cm
ironmonger@replicaprops the pictures of Henry Cavill wearing the key as a necklace and his proportions of his own height towards the proportions of the key.
Plus, all the prop replicas from XCOSER, Kate Golden souveniers, Hollywood History, Paulie form PROPBAY.com, Hasbro's own take on the prop, Mattel's halloween version, AND the Hot Toys MMS 200 MAn of steel 1/6th scale collectible included with a 1/1 scale kryptonian command key all approximate form about 6.7 cm to 8.2 cm.
For more clarification, go on ebay and see the listings and measurements, and even on etsy.com and most of all, see the 1/1 replicas of the kryptonian command key and how they measure up. None of the replicas go up to 9 cm. Do you think it is possible for you to scale it down for me please?
ironmonger@replicaprops do you think maybe you could sale the whole key down
for me in a different version where the height is about 7 inches (like it was in the movie)? or do you think you can maybe post your file for this on www.thingiverse.com to make it public or e-mail it to me at firstname.lastname@example.org ? Please and thank you
