FEATURES

  • SAFE MATERIAL WITH HIGH QUALITY - The food storage box is made of food-grade BPA-free silicone, which is non-toxic, tasteless, odorless, non-stick and easy to clean. The material has a temperature tolerance range of -40°C~200°C. And they're microwave, freezer, and dishwasher safe.

  • CONVENIENT DESIGN FOR YOUR EVERYDAY NEEDS - Collapsible design reduces the size by more than 50% when the meal prep box is not in use. They are foldable, stackable and the space-saving feature can help you save space in your kitchen cabinet and keep your closet tidy. The airtight lids keep your food fresh and the ventilation opening is great for convenient microwave heating.

  • ALWAYS READY FOR YOUR BACKWARD - Compared to old heavy glass containers, these space savers are lightweight and easy to carry. You can always bring one with you and start protecting our earth by using your reusable waste bin instead of a one-off plastic bento box.
