Crystal case v2s are designed to accommodate J-lace through the leash opening. If you want to install smithy or other larger diameter cord to your crystal poi lite v2, you can drill out the leash opening.
While flowlights are durable, a hard impact can break the shell in or outside of cases. We highly recommend that flowlights spun as poi are protected in a crystal case. These cases also enable you to add various weights (flowmass) to your poi heads.
