Last month, there was an exclusive LEGO Stranger Things Castle Byers build at the Flatiron and Leicester LEGO Brand Stores for the release of the LEGO Stranger Things The Upside Down (75810). Although the building instructions are readily available, there are some exclusive stickers that you can only get during the building event.
I have some good news as it looks like the US LEGO Brand Stores will be getting the Castle Byers building event later this month. According to my sources, registration for the event will start on June 10 and there will be a limited number of spaces. As with other building events, registration will be in-stores only. I do not know what day the event will be held but I let you guys know when I find out.
