>>9270077>>9270089>>9270126im surprised youre overthinking the accidental gifting 2 of the same lego sets. as if it were the same as getting 2 of a same action figure. It's like the others stated, build one as it is then build something else with the other. But why stop there if it's Lego, when you can build whatever you feel like? You don't even have to build what's on the box, maybe you can use the parts to freshen up a previous build, to build something that's from another set, or even something fanmade, using online instructions if you have the parts. You can even save them for future use.
