Two stainless steel ice cube trays, 12 large cubes total per cycle, each removed with a handle that flexes the tray instead of requiring a twist. ecozoi is based in Austin, Texas; the trays are manufactured in China from 304 food-grade stainless steel. No plastic anywhere in the tray or packaging. The large cube format melts slower, which matters for cocktails and cold drinks. Dishwasher safe.
