Think of our Cubelet as a relative of the 3D Organizer Cube . . . a close ​relative, as in adorable younger sibling. Clearly useful as an interior organizer (it nicely contains a laptop power brick), we’re also pretty certain some folks will also use it as an ultra-simple, über-tiny over-the-shoulder bag. Inside, it's as simple as it gets: no pockets or O-rings. Two exterior O-rings allow you to tether it inside your larger bag or pack, using one of our various colors and sizes of Key Straps. For stand-alone use, attach either a Wrist Loop to one of the O-rings, or a 5/8" / 16mm shoulder strap to both.
