While flowlights are durable, a hard impact can break the shell in or outside of cases. We recommend that all flowlights spun as poi are protected in at least a crystal case or our other flowpoi casings. These cases also enable you to add flowmass to your poi heads.
Facets in the crystal line up with the button to enable you to feel the button in the dark. Plus you can activate and change the modes of your flowlights without having to take them out of the crystals.
