The OCE Dashuai cup is a 40 oz tumbler: 1200 ml of insulated stainless steel with a straw and a food-grade silicone dust lid. It is built for iced water and cold drinks over a long day, on a desk, in the car or at a job site, for anyone who is tired of refilling a small bottle. Two prints: Small Floral and Green Vine.
- 1200 ml, about 40 oz
- Food-grade silicone dust lid
- Straw cup
- Small Floral or Green Vine
One fill, most of the day
Fill it with ice and water before you leave and you have a full morning of drinking on the desk, with no trips to the cooler. Big iced tea or lemonade fits too. It is a lot of cup, and that is the point of it.
Why the straw needs a cover
An open straw
- Collects dust on a desk or dashboard
- Picks up lint in a tote
- Draws bugs at a picnic table
With the silicone dust lid
- Closes the drinking end between sips
- Food-grade silicone, soft and flexible
- The drink stays clean for the next sip
Small Floral or Green Vine
Small Floral
A small flower print over the whole cup. See the swatch in the gallery.
Green Vine
A green vine print. Same cup, same lid and straw, a different pattern.
A fair read
Right size if
- You drink mostly water and want one fill to cover the morning or a shift.
- The cup lives on a desk, a workbench or the passenger seat.
- You like big iced drinks and hate running out.
Look elsewhere if
- You drink loose leaf tea. The OCE tea tumbler with strainer keeps the leaves out of the straw.
- You want Snoopy on your cup. See the OCE Snoopy flower tea tumbler.
- You need a narrow cup for a tight car cup holder. OCE publishes no base width for this one.
The details
Answered plainly
How big is a 40 oz tumbler?
This one holds 1200 ml, about 40 oz, which is several glasses of water in a single fill. OCE does not publish its height or base width, so check the gallery for its proportions.
Is it a tin cup?
No. The name got lost in translation. OCE calls it an ice cup, its term for a big insulated tumbler, and the body is insulated stainless steel.
Can I put hot coffee in it?
Iced coffee, yes. For hot drinks, OCE's listing gives no guidance on sipping them through the straw, so we recommend it for cold and iced drinks.
How do I keep the straw clean?
Keep the dust lid closed between sips, rinse the cup and straw at the end of each day, and run a straw brush through the straw. We found no dishwasher rating from OCE, so wash it by hand.
