Portal 2 Bookends
Officially licensed Portal Bookends not only feature test subjects going through portals, but they also keep your books in order!
The left side features half of a test subject going through an orange portal while the right side features the other half of the test subject coming out the blue portal. If you happen to be a test subject at Aperture Science, you're probably going to need these anyway. Bookends measure 5-inches tall x 4-inches wide x 2 1/4-inches long.
