Tronco 32 oz Glass Tumbler with Time Marker & Boba Straws

A 32 oz glass that keeps score. Drinking checkpoints are moulded down the silicone sleeve, with windows cut through it so the level inside is visible against them - a morning of forgotten water becomes obvious by lunch. The lid takes two nozzle widths: a 10 mm one for iced coffee and a 12 mm one that passes tapioca pearls. The borosilicate body is rated from -4 to 266 degrees Fahrenheit and shock resistant, the sleeve is non-slip, and the tapered base still clears most cup holders.

• Hourly checkpoints down the sleeve turn a hydration goal into a visible one
• Two nozzles in the box: 10 mm for coffee, 12 mm for boba pearls
• Borosilicate glass rated -4 to 266 F, shock resistant, BPA and lead free
• Stainless steel straws with food-grade silicone nozzles and a spill-proof lid
