How does it work?

How do I clean the cup?

Unscrew the plastic lid from the plastic collar. Separate the collar and sleeve from the silicone cup. Put everything in the top shelf of the dishwasher or wash it by hand.

How do I reassemble the cup after cleaning?

First – ​Position the plastic collar, threaded side up, above the silicone cup.
Second – ​​Deform the cup into a “C” shape and push it through the collar.
Third – ​Make sure the seal (ie. the top silicone ridge of the cup) sits adjacent to, and completely above, the top of the plastic collar.
Fourth – ​Screw the lid tightly onto the plastic collar to ensure an adequate seal is formed.

Can I put my cup in a backpack, purse or other bag while it's filled with a beverage?

We would not advise anyone to put the cup in their bag while it’s filled with a beverage. While liquid in all likelihood would not leak out, there is a chance something inadvertent could occur, and we wouldn’t want your cup to be to blame for a drenched bag. For example, if the stopper were to get snagged on a backpack zipper, it could dislodge, and liquid would spill out of the spout. You should feel completely comfortable collapsing your cup into a disk and throwing it in your bag when it’s mostly clear of liquid though (if some moisture and droplets remain inside the cup, they will not leak out when the cup is properly closed).

Are the materials BPA and phthalate free?

Of course! We use only FDA­ grade polypropylene (#5 recycleable) plastic and LFGB ­certified silicone rubber (LFGB is an EU standard that is considered even more stringent than FDA). We also use no adhesives during assembly.

Where are the cups manufactured?

The cups are manufactured responsibly in China. We share many of the concerns you have about manufacturing the cups there and have ensured the operations involved in manufacturing meet acceptable standards for quality, safety, fair labor, ethical business practices, and environmental responsibility. Our manufacturing and sourcing partner maintains certifications for Quality Management System (ISO 9001) and Environmental Management System (ISO 14001) standards.
