Its deep purple starry finish arrives with a planet bear pendant, and it suits long workdays, study sessions and anyone building a Starbucks galaxy collection.
- 910 ml (30.8 oz) per fill
- Stainless steel body
- Planet bear pendant included
- Reusable, fewer paper cups
Three reasons people pick it
One generous fill
A single pour of iced coffee or water lasts well into the afternoon. It feels hefty in the hand, and that is the trade for fewer trips to the tap.
Steel where it counts
The body is stainless steel instead of glass, so a knock against the desk or a tumble inside a tote bag is far less nerve-racking.
A bear from orbit
The planet bear pendant matches the galaxy theme and makes a plain drink cup feel picked out, which helps when it is a present.
Each order brings one straw cup plus its planet bear pendant.
Where it shines and where it falls short
Car cup holder check
Big cups run tall and wide, and nobody has published the base size for this one. Measure the opening and depth of your holder, then hold the base of the cup up to it before trusting it on the road.
The details
Short answers
How much does the purple galaxy straw cup hold?
Its capacity is 910 ml, roughly 30.8 oz, which lands a bit under a quart. Similar galaxy cups in the store list other sizes, so check the figure on this listing when you compare.
Does this Starbucks bear cup keep drinks hot?
No insulation is claimed for it, so plan on cold drinks. For temperature control, the vacuum insulated tumbler with straw or the color-changing insulated galaxy cup are better picks.
Is the planet bear pendant part of the order?
Yes. The pendant comes with the cup in this single listing, with no separate purchase needed.
How should I wash the galaxy cup?
Wash it by hand. Dishwasher use is unconfirmed for this cup, so treat the starry print gently with lukewarm water, a drop of mild dish soap and a cloth. Flush the straw as well, then let each part air dry.
