Twist-Seal Lidless Travel Tumbler — 300ml Double-Wall Insulated Straw Cup

No lid to lose, no spills to worry about. The AJ Euro Twist-Seal Travel Tumbler replaces the traditional lid with a revolutionary silicone membrane that twists closed over the top of the cup — forming a leak-proof seal in seconds. Twist it open to drink, twist it closed to seal. The membrane even holds a straw securely in place, making it the perfect travel cup for hot drinks, cold drinks, smoothies, and everything in between.

Double-walled construction keeps hot drinks warm for up to 2 hours and cold drinks chilled for up to 6 hours — and the 300ml capacity is the ideal size for a morning coffee, an afternoon smoothie, or a child's drink on the go. Safe for freezer use too, making it one of the most versatile travel cups available.

How the twist seal works

The silicone membrane sits over the top of the cup. Twist it clockwise to seal completely — no liquid escapes. Twist it slightly anti-clockwise to create an opening just large enough to drink from or fit a straw through. Twist closed again around the straw to hold it in place. No lid to misplace, no complicated mechanisms — just a simple, clever seal.

Ideal for

Commuters, parents, students, and anyone who wants a spill-resistant travel cup without the hassle of a conventional screw or click lid. The straw-compatible seal makes it particularly popular for children who prefer drinking through a straw but need a secure, portable cup.
