Food experts tell us that transferring our spices and herbs from their store-bought containers and into better storage increases the life of the seasonings. These jars will help in that regard, and we like that they have wide openings, allowing any size of measuring spoon to fit easily into the jar for ease when cooking. Airtight lids ensure that spices and herbs stay fresh. Each 2" diameter and 2 1/2" deep jar will hold a good supply of seasoning.
