The cake might be a lie, but this 1/1 scale Portal gun looks as real as one can get without being able to shoot holes in walls. 
This Aperture Science Handheld Portal Device is priced at ¥16,000 (US$208). It’s from Neca, the famed replica and prop maker.
Back in July 2011, Kotaku reported that Neca was working on official Valve action figures as well as a replica gun.
Pre-orders started online this week in Japan for an April release.
