Customer Questions & Answers
-
Question:
What materials are used in the Yumbox Cubi Thermal Jar?
Answer: The Yumbox Cubi Thermal Jar is constructed from high-quality stainless steel, known for its durability and resistance to rust. The jar also features food-grade silicone seals that enhance insulation, ensuring your meals maintain their desired temperature for hours. This combination makes it not only safe to use for food storage but also a long-lasting choice for both hot and cold lunches. -
Question:
How does the insulation technology work in this thermal jar?
Answer: The Yumbox Cubi utilizes triple insulation technology, which involves multiple layers of material designed to maintain temperature effectively. This means that hot foods can stay warm while cold items remain fresh and chilled. The insulation is effective for several hours, making it perfect for packed lunches, school, or picnics where temperature control is essential. -
Question:
Is the Yumbox Cubi suitable for both hot and cold meals?
Answer: Absolutely! The Yumbox Cubi is specifically designed to accommodate both hot and cold meals, making it versatile for any type of lunch. You can pack warm soups, pasta, or stews without worrying about temperature loss, or chill salads and fruits for a refreshing lunch. This feature makes it an excellent option for diverse meal planning. -
Question:
What is the size of the Yumbox Cubi, and how much can it hold?
Answer: The Yumbox Cubi is designed with kids in mind, offering a compact size that is perfect for little hands. It can hold a generous amount of food, making it suitable for a complete meal or snacks. Whether it’s for school, a day out, or sports events, this size ensures that kids can enjoy a satisfying meal without bulkiness. -
Question:
How easy is it to open for kids?
Answer: One of the standout features of the Yumbox Cubi is its easy-open design, equipped with a user-friendly lid that kids can manage themselves. This ensures that children can independently access their lunches at school or during outings. The hassle-free operation promotes confidence and self-reliance in young ones when it comes to handling their meals. -
Question:
Can I pack soups or liquids in the Yumbox Cubi?
Answer: Yes, the Yumbox Cubi is designed to handle liquids safely due to its secure airtight seal. You can confidently pack soups, stews, or even smoothies without the worry of leaks. This functionality is perfect for both nourishing lunches and quick snacks, making it a practical solution for various meal options. -
Question:
Is the Yumbox Cubi dishwasher safe?
Answer: The stainless steel body of the Yumbox Cubi is typically dishwasher safe, allowing for easy cleanup after meals. However, it's best to hand wash the silicone seals to prolong their lifespan. This feature makes post-use maintenance significantly simpler, ideal for busy parents and kids who want to spend more time enjoying their food rather than cleaning up. -
Question:
What makes the design of the Yumbox Cubi unique?
Answer: The Yumbox Cubi stands out with its unique rounded square design, offering a modern aesthetic while maximizing space efficiency. This shape is not only visually appealing but also practical for packing a variety of foods. Its thoughtful design encourages healthy eating habits by allowing a well-balanced mix of food groups within a compact container. -
Question:
How do you maintain the thermal qualities of the jar?
Answer: To maintain the thermal performance of your Yumbox Cubi, preheat or pre-chill the jar before packing food. Fill it with hot water or ice for a few minutes before adding your meal. This simple step helps to optimize insulation, ensuring meals stay at the right temperature longer. It's a great tip for anyone looking to maximize their lunchtime experience! -
