Premium Insulated Glass Tumbler with Lid & Straw - 20oz Ocean Blue - BPA-Free Reusable Water Bottle for Home, Office & Travel | by Keith Grinter | Perfect for Iced Coffee, Smoothies & Cold Beverages

These gorgeous glass tumblers have been handcrafted by New Zealand artist Keith Grinter in his Whangarei studio. Being delicately decorated with a mixture of coloured glass frits make each and every glass tumbler unique. Each tumbler has been hand blown, so there will be slight variations in shape, size, and colour. 

Keith is an award-winning glassblowing artist who works from his studio in Whangarei. Keith is particularly interested in the shard pick-up technique where he rolls molten glass onto shards of glass and wires forming spontaneous patterns, lines and surface design.
Keith taught at the Quay School of Arts, UCOL, Whanganui where he completed a BFA.
