I never wanted an elevator or fake tree or closing to my Kidkraft Supermold dollhouse so didn’t install them. They’re brand new, so the black squares came chipped, you could probably just flip them so they’re not visible though. Lots of extra screws so it should work together, I don’t even know what the bag and white pieces do so they’re yours to do with. I have the big booklet of instructions.
I sell lots of dolls, doll clothes, action figures, mini brand stuff, so feel free to make offers on my other stuff for combined shipping.
