Seal Cup Medium


Plastic-free and leak-proof, the Seal Cup™ Medium is a versatile, durable lunch container for packing meals and snacks to-go.

The Seal Cup Medium and all our Blue Water Bento collection lunch and snack containers are designed FOR the ocean and  BY the ocean. The beauty of our oceans has inspired all our lunchbox designs, and we make an effort to include only non-toxic, sustainable materials to limit our impact on the world's waters. Sneak a peek at the behind-the-scenes lunch container design process.

Since our Blue Water Bento lunch containers are designed FOR the ocean and BY the ocean, it's the beauty of the nubby ridges found on seashells inspired the texture of the Seal Cup Medium's blue silicone lid. Using this dishwasher-safe, reusable lunch container, you can help reduce the amount of waste you produce daily.  

In addition, the Seal Cup Medium makes your lunches greener and our oceans cleaner by keeping dangerous plastics and other toxic materials out of your lunch and our oceans. Learn more…
