Streamline Discs is a collection of single mold / single plastic discs from the makers of MVP and Axiom. They look great with stock multi-foil stamps at an economy price. MVP's been making way more complicated GYRO overmolds for years. They've perfected their techniques and have now applied them to this solo-mold line. Streamlines have precision, 3-foil stamping, smooth edges, and consistent domes across colors.
