Using this cup is super easy. Just open the black anti - spill lid and fill it with your favorite drink. It can hold about 470 ml, enough for your daily outings. When you're done using it, make sure to clean it with mild soap and warm water. Don't put it in the dishwasher as it might damage the bamboo material. Also, be careful not to drop it, as the bamboo could crack. Store it in a dry place to keep it in good condition. Enjoy your travels with this unique cup!
