This is a set of 6 recycled glass jars with bamboo lids and labels! Each holds 5oz. The jars: recycled Yoplait Oui yogurt jars. The lids: Bamboo with silicone gaskets. The labels: Black fancy-shaped, write-on self adhesive labels. These are great for storing spices (which is what I use them for), beads, paper clips, sewing notions, you name it! Lids fit pretty securely, but I would not call them spill-proof. Help to reduce and reuse by picking up these jars with a new purpose! 😊
