Recommended by Serious Eats for their style but also their function: “glass allows coffee to cool more quickly than ceramic, so these mugs are perfect for impatient sippers.” The extra-thick borosilicate glass is durable and can rapid handle temperature changes like a champ. • Sold as a pair (2 mugs) • 11 oz (325 ml) • 3.25" x ⌀3.25" (80 mm x ⌀80 mm) • Part of the Slow System • Recommended by Serious Eats
