The AIZ Carafe and ZAI Tumbler are hand-blown from borosilicate glass — a harder, more heat-resistant glass than standard soda-lime — made by artisans through Powered by People's network. The tumbler nests on top of the carafe, which keeps the set compact on a nightstand or desk. Capacities are 33.8 oz (carafe) and 10 oz (tumbler). Both handle hot and cold liquids.
The OZAIZ design doubles as a candle holder, rock diffuser, or fragrance vessel when you're done using it as drinkware — a genuine second-use case rather than a disposal plan. Borosilicate glass is accepted at many glass-recycling drop-off sites, though not universally curbside; check your local program before assuming. Country of manufacture and packaging materials are not disclosed by the vendor — we've asked and will update this listing when we hear back.
