The Smithsonian launched a Kickstarter campaign last week to raise $300,000 to help preserve the slippers that whisked Dorothy back to Kansas at the end of the movie.

Officials say they reached their goal late Sunday night thanks to more than 5,300 supporters in 41 countries across six continents. They say they’ll announce a stretch goal Monday involving a character who traveled down the yellow brick road with Dorothy.

As of Monday morning, the Kickstarted had raised $300,935.

The slippers have been one of the most beloved items at the National Museum of American History. The Smithsonian wants to put the money toward a technologically advanced display case that will preserve them for future generations.

The campaign, dubbed #KeepThemRuby, offers donor rewards ranging from T-shirts and tote bags to replica slippers and behind-the-scenes tours.

This isn’t the Smithsonian’s first Kickstarter drive. In 2015, it raised $700,000 to conserve Neil Armstrong’s spacesuit.
