The reheatable & space-saving meal box!

Cold? Hot? No problem! Go from fridge to lunch for cold options like salad or fruit, or simply pop the vent on our 4-cup/1 L Rectangular container to warm your meal evenly in the microwave. Plus, its stackable, modular shape maximizes refrigerator space.


Enjoy the comfort of healthy, homemade food any time. ​From your fridge directly into the microwave, our CrystalWave® PLUS Rectangular container is the perfect reheating solution.​

CrystalWave® containers are made of a heat-resistant material, microwave safe up to 248°F/120°C. The lid's valve allows steam to escape during reheating, preventing any potential pressure build-up.​ Pop the vent and leave the seal in place to prevent splattering and spills when reheating. 

This PLUS container features a textured, scratch-resistant base, while the Stain Guard coating on the inside protects your container from stain-prone sauces.

This 4-cup/1 L Rectangular microwave container holds a generous portion of your favorite foods, including veggies, pasta, casseroles, desserts, and more.


  • Microwave safe: heat resistant up to 248°F/120°C; maximum wattage of 650
  • Splatter-free microwave: The seal prevents splatters during microwave heating while its valve prevents pressure build-up by letting steam escape.
  • Stain Guard coating: Our unique Color Control technology helps prevent staining on the inside of the container from ingredients like tomato sauce or turmeric, so your CrystalWave® PLUS will always look just as good as the day you bought it.
  • Textured surface: resists scratches
  • Save money and time by skipping the cafeteria or restaurant lines, and bring healthy, homemade food with you to work or school.​
