Northstar Electric Blue Stardust (Light Cobalt over Heavy Blue Stardust) WonderTube (WT073) - Ends Knuckles Tube Transitional Knuckle End

Electric Blue Stardust is Northstar's WT-073 WonderTube: a layer of Light Cobalt drawn over Heavy Blue Stardust, so the cobalt reads bright and transparent while the Stardust base keeps its sparkle in the depth of the wall. These are the cut ends and knuckles left over from production runs of that tube — short usable lengths of the same glass at a fraction of the price. Ideal for test pulls, marbles, small encasements, or any job where you need the colour but not a full-length tube. Lengths vary; sold by the pound and not available for backorder.
