joyjolt caleo

Caleo glasses are made from borosilicate glass — a stronger, heat- and condensation-resistant type of glass commonly used for thermal stability.

Caleo glasses are offered in several capacities, including 5.4 ounces, 10 ounces, and 13.5 ounces.

Caleo sets are commonly sold in small groupings, most frequently as 2-piece and 4-piece sets.

Product details list a temperature tolerance of up to 350°F.

The double-wall design creates an inner chamber that visually suspends the liquid, helps maintain beverage temperature, prevents condensation, and keeps the outer glass cool to the touch.

Product descriptions label the Caleo collection as mouth‑blown or hand‑blown glass (listed in the product details as mouth blown/hand blown).

They’re marketed for both hot and cold beverages, with examples including tea, latte, espresso, cappuccino, macchiato, juice, smoothies, and water.

Dimensions vary by capacity: heights range roughly from 3.75 inches to 4.5 inches and widths from about 2.5 inches to 3.5 inches. The design also features an angled, curved base.
