This set of spice jars features a black color and is made of food-grade, reusable plastic material, with each jar having a capacity of 250 milliliters (8.7 oz). The package includes 30 plastic spice jars with shakers, each equipped with a black screw lid that has a double-sided flip lid design. The flip lid allows for two independent uses: one side with holes large enough to let dried herbs pass through for sprinkling, and the other enabling precise seasoning measurement without removing the entire lid. The spice containers have a smooth jar mouth, a high-permeability transparent bottle body, and a simple overall design. Each jar weighs approximately 0.08 lbs, making them lightweight and easy to carry—suitable for kitchen use as well as outdoor activities like picnics or barbecues. The jar body is made of quality plastic, ensuring strength and durability, while the tight-fitting structure between the smooth jar mouth and the lid prevents leakage. Additionally, the jars are easy to clean due to their simple design and plastic material.
