Using this dinnerware set is a breeze. When you're packing, simply collapse the bowls and cups to save space in your pack. Once it's mealtime, just unfold them and they're ready to use. For a secure hold, grip the rim of the bowls or the upper rim and central ring of the cups. When using spoons, note that the unique curve of the bowls is designed to match Sea to Summit spoons for a better dining experience. As for maintenance, you can wash this dinnerware with mild dish soap and water. Since it's made of high - quality EU food - grade materials, it's durable, but try to avoid using abrasive cleaners as they might damage the surface. Store it in a dry place when not in use to keep it in good condition.
