Most glass cups with lids are hiding something. A silicone gasket. A rubber ring. A plastic seal. They call themselves plastic-free and bury the silicone in the fine print.
VITRI's lid seals glass to glass. No rubber, no silicone, no plastic. Just glass meeting glass, the same way laboratory equipment has worked for over a century. It is patented because nobody had done it in a consumer cup before.
The result is a lidded tumbler where your drink touches nothing but glass, from the base to the last sip.
The double-wall keeps drinks at temperature longer. The lid adds insulation and splash resistance, making it the cup that goes where you go. 10oz with the lid. 12oz without.

The Glass-to-Glass Seal
Most lidded glass cups aren't fully glass. They use a silicone gasket or rubber ring to close the gap between lid and body, then market themselves as plastic-free anyway. VITRI's lid closes a different way. The lid and base are shaped to meet glass directly against glass, the same sealing principle used in laboratory glassware for over a century. No gasket, no synthetic material bridging the two pieces. The seal holds because of precision, not because of a rubber ring doing the work. That's what makes it possible to say your drink touches nothing but glass, from the base to the last sip.
Why Borosilicate, Not Plastic
Borosilicate glass is the same material used in lab equipment and premium cookware, chosen for its clarity, durability, and resistance to thermal shock. It handles hot and cold drinks equally well without cracking or leaching chemicals into the drink that could affect taste or your health. Many tumblers marketed as glass are actually glass paired with a plastic lid and/or a silicone seal, meaning the beverage isn't always touching glass. VITRI's all-glass construction, lid and seal included, keeps every part that contacts your drink made of the same inert material.
Your Drink, Wherever You Are
The All-Glass Lidded Tumbler is built for daily use in the home and beyond. The sip-through lid adds splash resistance for the yoga studio, the car, or the office, and along with the double-wall glass, helps keep drinks at temperature along the way. It's sized to fit most standard cupholders. Because the seal is glass-to-glass rather than a gasket, there's no rubber lining to trap odor or grow mold and mildew behind. Since it's all glass, a quick rinse is enough to keep it fresh between cleanings.
