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.
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).
