Made of 100% food-grade silicone, this microwave-/dishwasher-/freezer-safe travel bowl is built for adventure. The slip-resistant outer is grippy for easy use and the inside is polished smooth to create a comfortable eating surface. This easy-care bowl will not break, crack, chip, fade, or scratch. And, it folds up into itself so you can easily travel with it-in fact, it folds up so small you can carry it in your back pocket. Holds a full liter of water, and when you're not using it as a dog bowl, you can pop it around to create a 2-liter bucket. This dog bowl insulates hot and cold contents, and is BPA free, and FDA approved. 100% silicone. Dishwasher safe.
