To keep your lashes clean and dust-free for the next time that you wear them, it’s important to store them in a protective container. You don’t have to buy a special container, though -- save the plastic case that holds the lashes, as well as the tray with the half-moon shapes for the lashes to curl around. If you lose or misplace the packaging from your lashes, you can purchase reusable protective cases from beauty supply stores and online sites. They often hold more than one pair of lashes, so you can store all of your lashes in one place. Once the lashes are in their packaging, it’s important to store them in the right spot. Heat and strong light can warp the lashes, so you should keep them in a cool, dark spot, such as a dresser drawer, until you want to apply them the next time. Avoid storing your eyelashes in the bathroom, which often gets hot and humid.

Summary:
Save the plastic packaging that the lashes come in. Place the lashes in a cool, dark location.
