The tray is made from silicone, not those impossible to crack hard plastic sort, and has six smaller carbonite cubes and one large cube. It’s hard to tell what size the cubes are, but I bet the larger one is more for a punchbowl. I think I would put some grape juice in there and make them look black like the film’s carbonite.
In a word? Cool... :P
Only $9.99 too!
