This is a new, un-opened, Stranger Things LEGO set that is no longer available in stores.

The box shows minor signs of edge wear as shown in photos, but it has never been opened.

From Lego.com: "Fans of the global hit Netflix original series will appreciate the authentic details of this highly collectible LEGO® Stranger Things toy – 75810 The Upside Down. This sturdy, brick-built model can flip between the real world and The Upside Down. The design of the model's building instructions makes it a great shared building experience with friends and family. The Byers' house features Will's bedroom, the living room and the dining room. The Upside Down version of the house, from an alternate dimension, features all the rooms from the real-world model but with a dark, vine-covered, dilapidated look that fans will instantly recognize from the series. With 8 Stranger Things figures, each with its own accessories, this playset makes a great gift for Stranger Things fans who will love to build and display this model to show their passion for the series."
