This innovative food storage piece features a bamboo lid that doubles as a cutting board. The lid has a silicone lining and silicone band to ensure food is kept secure in the container. The item is made of 55% bamboo fiber and 45% resin. This container is not suitable for liquids and must be used for solid food only. This item is not suitable to be used in the microwave. Due to the nature of the bamboo material, variations in laser imprinting quality may occur. Through a partnership with 1% For The Planet, one percent of sales of this and all EcoSmart products will be donated to nonprofits dedicated to protecting the planet.
