Blue Fish is a new design from Rolf Glass that features eleven whimsical fish (including the signature Rolf Glass wayward fish) clustered together. Each design is diamond-wheel cut onto blue “transition glass.” “Transition glass” is the glass made by bottle manufacturers when switching glass colors, in this case from blue to clear. This glass, that would typically be scrapped, is repurposed by turning them into these cute little 14oz. tumblers. All glasses are dishwasher-safe and proudly made in the USA.
