Yes, every Elfbar e-cigarette has an expiration date, which is printed on the packaging. Depending on the product, Elfbars can be enjoyed for one to two years from the production date. Products with an expired date may have quality problems and should no longer be consumed. The reason for the expiry dates is the e-liquids they contain, which can lose their freshness over time. The batteries of disposable vapes can also discharge over time. The Elfbar Mate pod system, which is not pre-filled with liquid, has no expiration date.
