The design of the Perle tumblers, now an iconic Zafferano product, combines ancient glass craftsmanship with contemporary design, creating tumblers with irresistible charm. The delightful contrast between transparent glass and vitreous paste is achieved through the artisanal technique of applying and breaking the spiral pattern, expertly performed by skilled glassmakers. Available in fourteen vibrant shades, these mass-colored glass tumblers are mouth-blown and handcrafted, and are dishwasher safe up to 140°F(60°C). Perfect for enhancing any table with style and bringing joy and color to your home! The tumblers are available in sets of two (same color) or sets of six (assorted colors).
