23rd March, 2017 Buy Ninja PVC Buffer Ring Moar visability! "I bought my Ninja Poi before they sold clear PVC rings so it came with the standard black ones which absorb some light. Its really not noticeable at night but I figured I would get some of these just to make the POI look nicer overall. They are a bit tougher than the black rings to get on but definitely improve the overall aesthetics of the POI and I couldn't be happier." Matthew Bournival, USA.
