Up for sale are 5 JABO "UV" Black Light Swirl Shooter Marbles 1" ~ Splashy! ~ HIGH GLOW! Blue and White.   These are in mint minus condition with "as made hit marks" from the assembly line drop (these are heavy), but they look great.   They all measure close to 1" with a caliper.   They glow VERY bright in black light, my phone doesn't do them justice really.   Thanks for looking and best of luck!
