Lighted snowman jars are plug-in indoor items that use incandescent mini bulbs (examples list 11 bulbs), feature non-blinking lights, and include a cord lead (example: 66 inches). They do not require batteries.
Widths and depths commonly fall between about 3 inches and 8 inches, with examples such as 3×3, 4.25×4.25, 6×6, 6.12×6.12, and 8×8 inches.
Some snowman jars have secure or airtight seals or lids that help keep cookies and baking ingredients fresh. Other decorative hat-style lids may not include a rubber seal.
