Up for sale is a Set of 6 Different Jabo HIGHLY UV Reactive 1" Glow Swirl Shooters Black light Marbles.    They are all in Mint minus condition as they have the hit marks from the assembly line on them (there can be a good amount of these on some) but they are still awesome as you can see.   6 distinct types (families) included and half are highly reactive to UV/Blacklight (my camera doesn't really do them justice).  They all measure around 1 inch in size by caliper.    Just remember they will have dings as mentioned.   Thanks for looking and best of luck!
