Factory Entertainment's TNG Medical Set Replica has been copied directly from surviving resources in the CBS archives to ensure accuracy. Our development team also spent many hours analyzing footage to fine-tune the details. This 1:1 scale set replicates two iconic props used by 24th century physicians in Star Trek: The Next Generation. It consists of a Hypospray (with interchangeable vials) and a Hand Scanner. Both feature electronic light and/or sound effects and are crafted with heavy diecast metal bodies. Each numbered limited edition museum quality replica set comes with a wooden presentation case, cast metal plaque and a certificate of authenticity/prop story booklet and will make a fine addition to any Star Trek collection. The Hypospray and the Hand Scanner each operate on three LR44 batteries (included). Prototype images shown. Final product may contain user fillable vials. Final product may vary.
