This is a pair of officially licensed bookends themed by the popular video game series Portal. Each bookend measures 4 x 5 x 2.25 inches, and as we can see from the images, the left bookend features a half of a test object going through an orange portal, while the right side features the other half of the test object coming out from the blue portal. The Portal bookends are made of shiny and durable aluminum, and comes with non-slip rubber padding on the bottom in order to keep your books in place.
