Diamond Select Toys has released some Star Trek: TOS props and they are available now in exclusive sets from the Nerd Approved Shop!
You can choose between two sets (or just get both of them): one has a gold phaser and communicator and the other has a white phaser and a medical tricorder. They are perfect for your collection or to carry around as props with your TOS costume. I recommend using the tricorder to scan co-workers while muttering to yourself and shaking your head.
Each item has sound effects, lighting where applicable, and is closely modeled after the on screen props from the show.
Check out the white phaser and the tricorder after the break.
