ECOlunchbox Warranty

Our lunchboxes are built to last and we ensure every product is held to the highest standards for quality and food safety. All ECOlunchbox products have a one year warranty against any manufacturer's defects.  Occasionally, there are defects in the steel that can occur when the steel is stretched around the lunchbox form and a small section of the steel sheet gets thinned past the desired threshold.  We check for such defects during the production process to prevent them from being distributed to customers.  In the rare event that you receive a lunchbox with such a defect, we will gladly replace it.

Normal wear and tear are not covered under warranty. Normal wear and tear includes dings, scratches and clips that need to be tightened/adjusted. If the clips on your Tri Bento or ECOlunchbox Three in One have gotten too tight or too loose, please see our FAQ page for instructions on how to adjust them to your liking or click here.

Our artisan textile and organic cotton canvas lunchbags can be machine washed on cold and tumbled dry. We suggest using a delicates bag to protect the straps and buttons when washing by machine. If the straps and the button get tangled in laundry, the buttons may come off. We do have extra buttons we can supply upon request if you need one. But loss of a button or a damaged lunchbag strap is not covered under our warranty.

The silicone lid on our Splash Box is 100% water and air tight. This makes for worry-free use, but please don't pack the box with the lid sealed into an unpressurized cargo hold when you are travelling via airplane. Bring it as a carry on. The silicone lid, due to its tight seal, may be prone to splitting due to the change in air pressure. This is not covered under our warranty.

If you have a warranty claim, please email us at 

ECOlunchboxes are made by Matsekk, Inc. We are based in the San Francisco Bay Area.
