“Hi,
Great product, made from rice husks which is organic by-product. Great concept, even micro oven unable. I bought it to replace my plastic (fossil fuel) lunch-box, unfortunately I can not use it due to its poorly designed seal. It doesn't matter how carefully I place the seal and how many rubber bands I use, it always leaks (both oils and water). My plastic lunch-box never leaks (it's "Click&Click" brand) because it has a well designed seal.
Regards Filippo.”
