Great space set
Colorful space set appeals to both girls and boys. Slightly changeling but manageable without adult assistance which makes child confident and proud.

Why is this set hard to find?
I’ve searched in the wild for this set for a year and finally caved and bought it on your site as I’ve never seen one in a retail setting or online e commerce retailers. Kudos it’s an amazing set. The new Lego city space line is the chefs kiss of Lego city space sets. This lab specifically was purchased so my son and myself could build and play along with the other wonderful matching sets in the Lego city space line.

City space science lab
It was not complete with the pieces. I had to go online and that was not successful at legos customer service I bought 2 sets the one set was complete but the second set was not complete for another Grandchild. Frustration! I seem to get a lot of their sets that aren’t complete with the pieces. It’s cute, has 4 books to assemble. Hardly any extra pieces in this.
