The storage jars have thick side walls for added durability and stability. The clear glass jar features a wide mouth opening for ease of access and scooping, making the jars perfect for storing masalas, sugar, paperclips on the counter-top or in the pantry and for storing or showcasing craft or home decor items throughout the home. These metal lids are rust proof. The lid is easy to remove but has a strong seal that ensures the jar’s contents stay fresh. The food grade glass jar is lightweight.
