This Bitzy Bob Standard does have two color snaps - dark inside and light outside. (I liked the lighter color better! Does not affect use - just wanted to give you a heads up!
How Bitzy Bobs work: Just twist your remaining floss "bitz" and pat onto the felt station. The friction makes the floss cling. Handy zipped clear pocket for your threads or tools. It also has a magnet to stage some needles or your tiny scissors. At the end of your stitching session, snap closed and you'll be ready for the next time! **scissors, chart and floss not included
