Though you’re never too old to play with LEGO bricks, you might be running out of storage space for all your massive Star Wars ships and Hogwarts halls. If you’re looking for an easy way to ensure that your sets end up in the hands of worthy secondhand owners, consider donating them back to the LEGO Group.

Geek.com reports that LEGO has teamed up with Give Back Box, a sustainability organization that provides shipping services to charities, for their new LEGO Replay initiative, where they’ll send your used bricks to either Teach for America or Boys & Girls Clubs of Boston.

To encourage people to part with their toys, LEGO has made the donation process as hassle-free as possible. Essentially, they’ll accept whatever LEGO bricks you have—any number, any size, any condition. You don’t have to donate complete sets, you don’t have to sort the bricks, and you don’t even have to wash off the dust. Give Back Box employees will inspect all contributions by hand, thoroughly clean them, and ship them off to the next generation of builders. All you have to do is toss your bricks in a box and print out a free shipping label here.

“Learning through play can have a tremendous impact on a child’s cognitive development,” Susan Asiyanbi, Teach for America’s chief operating and program officer, said in a press release. “Children develop fine motor skills, think creatively, and can learn how to problem-solve through teamwork. But not everyone has access to such resources.”

Even if you’re still an avid LEGO builder yourself, this could be the perfect opportunity to give some of your easier sets to the rookies, and make room for your next epic LEGO project—like this 1771-piece Yoda.
