It’s a very geeky Christmas this year. Great for the holiday season or anytime you want to nerd up your home a little bit, these Portal Companion Cube String Lights are a jazzy edition to your decor, gamer. Officially licensed by Valve, each string is 10 feet long with 10 cubes (that’s an average of 1 cube per foot- someone check my math on that one). Perfect for wrapping around your Christmas cube or even tree.
