The Tower of Clips is made from remnant steel from the tabletop industry. Yeah, we were unaware that such steel existed, too. But, we're glad that we know now! This clever design allows you to store notes, gift cards, pens, pencils, coupons, and even your keys in a fun, movable display. Each flat, non-toothed clip can rotate 360 degrees and features a super-strong spring that won't lose its grip.
