Why it rides along all day
A big fill
With this much room, a large iced coffee and plenty of ice go in together, so the refill can wait.
A finish that moves
The purple gradient reads like a night sky and changes color with temperature, so the galaxy looks new with each drink.
Small extras that count
A reusable stainless steel straw, a planet-shaped stopper that caps it, and a pendant that clips onto your bag.
This listing has one version: the 700 ml (24 oz) cup sold with its pendant.
Where this cup works best
Treat the lid gently
The seal lives in the lid, so wash it by hand to keep it snug. Flush the straw after sweet drinks and let every part dry before reassembling.

- Like a design that looks different hot or cold
- Are shopping for someone who loves space themes

The details
Straight answers
Is 700 ml (24 oz) a big size for a Starbucks tumbler?
Yes, it is generous. 700 ml works out to roughly 23.7 oz, enough for a big iced coffee with ice, or water for a whole morning.
Does the color-changing cup work with hot and cold drinks?
Yes. The insulated steel body takes both, and the gradient shifts with temperature. With hot drinks, sip slowly through the straw.
What comes with the cup?
The cup and lid, a reusable stainless steel straw, a planet-shaped straw stopper and a pendant for a bag or backpack.
Is there a version with a bear pendant?
Yes. The galaxy straw cup with a bear pendant shares the purple night theme, while the Purple Cherry Blossom drinkware swaps stars for flowers.
