Woah that man is going right through your books! Even if you’re not familiar with the popular Portal video game series (which essentially involve puzzles that have you jumping a man through a series of portals), these cool Portal Bookends would still make an attractive addition to your bookshelf. Made of aluminum with rubber feet to keep it firmly in place. You don’t read physical books anymore? No problem, use them to hold your stack of Kindles upright.
