Can this tumbler hold hot coffee or tea?

Not recommended for hot beverages when the lid is in the locked position. It's designed for cold and iced drinks, including carbonated ones.

Will it leak if I throw it in a backpack or tote bag?

When the lid is closed and locked, it forms a complete seal that prevents leaks with cold and iced beverages, including carbonated drinks. The flip mechanism must be in the locked position.

Does the straw come out for cleaning?

Yes, the straw is removable so you can wash it thoroughly. The metal core and silicone mouthpiece can be cleaned separately from the tumbler body and lid.

How much ice and liquid should I put in if I'm using it for soda or sparkling water?

Use a fifty-fifty ratio of ice to liquid and leave some headspace at the top. This allows room for carbonation pressure without compromising the seal.

Will this fit in a standard car cup holder?

Yes, the base is sized to fit most vehicle and desk cup holders without wobbling or sticking.

Straw tumbler with a flip-down cover that locks shut when you move

Most straw tumblers either leak when tipped or force you to unscrew a cap every time you drink. This one uses a flip mechanism that opens one-handed and closes into a full seal, so the same lid that keeps your drink cold also keeps it from soaking your bag. The covered straw matters more than it sounds like it would—no dust, no bag debris, no wondering what touched it since the last sip—and the locking seal works even with fizzy drinks if you leave room for pressure. If you've avoided straw cups because of spills or been annoyed by exposed straws, the flip-and-lock design solves both without adding steps.

The details

A straw tumbler designed to travel without spilling. The lid flips down to expose the straw when you drink, then locks into a watertight seal when you close it again. Cold and iced carbonated beverages stay contained even when the cup tips over or gets tossed into a bag.

The straw itself sits covered until you flip the top open, keeping it cleaner between sips. Silicone wraps the mouthpiece for comfort, and a metal core reduces the amount of plastic in contact with your drink. Double-wall insulation holds temperature for more than twenty-four hours.

The base fits standard vehicle cup holders. At twenty ounces, it holds enough for a morning commute or a few hours at a desk without constant refills. Stardust colorway features a speckled metallic finish.

Suitable for ages six and up. When using carbonated drinks, fill halfway with ice and leave headspace. Not intended for hot liquids in the locked position.
