Crafted with high quality Borosilicate glass & Acacia wood lid with silicone insert. Borosilicate glass is a type of glass that contains boron trioxide which allows for a very low coefficient of thermal expansion. This means it will not crack under extreme temperature changes like regular glass. Its durability has made it the glass of choice for high-end restaurants, laboratories and wineries. The lid is made from Acacia wood, ethically sourced. These pantry jars provide a clean, safe and airtight protection for dried goods. These storage jars look amazing in any kitchen or pantry, they are extremely functional, easy to clean, and perfect for package free bulk foods.
