This huge 49.3mm marble is American made by Funhouse Glass! It's featuring his squiggle hypno design with a rainbow of colors! This marble is marvelous and is one of the biggest ones currently in our possession. It is blue on the backside with some dot stacks surrounding the middle. This one is signed and dated! The stand is not included but we can include it for $5 more. (Sorry for the reflection, these pictures were taken outside)
