21 limited-edition gifts you can only get in 2018 - or until they sell out

The Insider Picks team writes about stuff we think you'll like. Business Insider has affiliate partnerships, so we get a share of the revenue from your purchase.

Finding a unique gift isn't easy. That's why we dig through the internet's vast offerings to suggest cool gift ideas you haven't already thought of, like thoughtful personalized gifts and gifts from a site with "uncommon" right in its name.

Another way to guarantee the special feel of a gift is to find limited-edition products. Since only a certain number is made and they're often done in collaboration with other brands, they possess a cool factor that regular gifts can't replicate. Given their exclusivity, it's less likely that everyone is going to emerge in 2019 wearing the same pair of shoes or backpack.

These 21 gifts aren't going to stick around long, and once they're gone, they're gone forever, so if you really want to impress your recipient this year, don't hesitate to pick up one of these limited-edition products.
