Capacities vary widely: small spice jars are often listed as 4 oz, tiny cellars about 2.82 oz, mid-size glass canisters are shown as 24–48 fl oz or 38 fl oz, and large storage canisters go up to about 105 fl oz.
Clear glass bodies let you view contents at a glance. Some small cellar sets are explicitly described as stackable or designed to stack, which saves counter or shelf space.
Four-ounce jars are often used for spices and dried herbs, baby food, party favors, pantry organization, and storing small craft items.
Reviews are mixed: some praise airtight or gasket-style lids that keep contents fresh, while others report lids that aren’t tightly sealed or that can come off.
They’re commonly kept on countertops or in pantries for spices, herbs, and cooking ingredients; some listings describe them as suitable for display on shelves or for use next to the stove.
