To use, open the airtight lid by lifting the flap, then fill the container with dry foods such as cereals, pasta, flour, sugar, coffee, nuts, or snacks. After filling, close the lid by pressing firmly so that the sealing system activates and keeps food fresh for longer. Place the containers in the cupboard, refrigerator, or pantry, where their rectangular shape helps save space and organize your kitchen efficiently. To clean, wash the containers by hand with warm water and detergent, and gently clean the lids and let them dry completely before reuse. If you have labels applied, you can rewrite the contents whenever you change the stored food for quick and convenient identification. Spice Jars
