【Integrated Spoon】: There is a built-in groove on the lid for folding stainless steel spoons. This eliminates the need to remember individual utensils, making the entire kit compact and very convenient for dining on the go, at work, or at the gym. 【Separate Storage Ensures Freshness】: The accompanying small container has a separate compartment that allows you to separate dry ingredients from wet ingredients until you're ready to eat. This ensures that the texture remains crispy, prevents moisture, and makes the taste of each meal fresher. 【Leak Proof and Safe Transportation】: The main tank cover and individual ingredient containers are equipped with airtight silicone rings. This creates a reliable and leak proof seal that prevents liquid substances from spilling out, allowing you to feel at ease during your commute. 【Stackable Design】: The design of the jar is stackable, with the top cover firmly installed at the bottom of another jar. This maximizes the vertical space of the refrigerator or cabinet, making it an ideal choice for preparing multiple meals in advance without causing confusion. 【Multi Functional for Various Meals】: This set is made of durable wide mouthed glass jars and silicone, not only suitable for overnight oats. It is also suitable for yogurt jelly, chia pudding, simple salads, and even snacks such as potato chips and salsa, supporting a wide range of healthy eating habits.
