All glass noodles, also known as cellophane noodles, are vegan-friendly. The noodles themselves are made from starches such as mung bean starch, potato starch, or sweet potato starch, without any animal products. It's always a good idea to check the ingredients list on the specific package you are purchasing, as different brands may have variations or additional ingredients. But as long as you are buying dried glass noodles, they should be suitable for a vegan diet.
