S-hooks are a spatially efficient way to hang clothes in narrow closets, but the Q-Hook's minor design addition significantly improves upon the simple system. Rather than just draping over the top of a clothing rod, the Q-Hook adds a curl that wraps around the entirety of any clothing rod, keeping the hanger in place when people remove the item hanging from it.
Though Q-Hooks stay firmly hanging in the closet when S-hooks often fall, the clever hooks are still easy to add to and remove from one's closet. The curling portion of the design clears enough horizontal space to slip onto a rod when it's turned sideways. However, that sideways orientation would never happen during normal use.
The Q-Hooks come in three colors: pink, white, and blue.
