Set of four Olive 16oz Wine Punts The Original Wine Punts drinking glasses are all hand made from repurposed wine bottles collected from our local community. Giving new life to bottles that might otherwise end up in landfills. Each and every Wine Punt is fire polished then annealed for the smoothest finish and greatest durability. By fire polishing we ensure that each glass will have a smooth finished rim that is consistent with the rest of the glass. This process also prevents cracking and chipping from normal use. Microwave and dishwasher safe. *Volumes are approximate because of variations in bottle attributes.
