The Handy Tumbler, Set of 6 from Zafferano America unites an open, ergonomic shape with practical applications. Designed by Federico De Majo, each tumbler is mouth-blown from soda-lime glass and features slender vertical striations, combined with a crimped-in side that offers easy gripping. The flaring shape and side seam provide positive retention, while also complementing the rest of the tumblers in the set and maximizing storage space.
