Enjoy a Hot Homemade Meal Anywhere

Stop settling for cold lunches at work. The Nuvia Haven Heated Lunch Box is a rechargeable, self-warming bento box that gently heats your pre-cooked meals to 80°C (176°F) — the ideal temperature to enjoy a warm, satisfying lunch wherever your day takes you. With a built-in timer function, simply charge it fully, load it with your cooked food, and set the timer to start warming 1 hour before your meal. By lunchtime, your food is perfectly warm and ready to enjoy — no microwave, no office kitchen, no problem.

⚠️ Important Use Notes: This lunch box is designed to keep cooked food warm, not to cook raw food or rapidly reheat cold food. For best results: fully charge → add cooked food → activate 80°C warming mode 1 hour before eating. Keep upright during use to prevent leaks.
