Whether you work in a doctor’s office, behind the counter at the Post Office, in a cavernous warehouse, in a fast food restaurant kitchen, or as a restroom attendant, you’ve got to get a sheet of these stickers and transform your space into an official Aperture Science test chamber.
Each sheet of 9 stickers is individually approved by GLaDOS herself, and is made from durable waterproof/UV resistant vinyl, so you can stick them anywhere – even on your car, or better yet, on random workout equipment at the gym. They sell for $12.99 (USD) a sheet over at ThinkGeek. Handheld Portal Device and Companion Cubes sold separately.
