"The ship in a bottle was clearly designed for a couple, when you need to build at least two of everything. It was brought as a gift and my partner and I sat down for 3 hours and spent some quiet time helping to piece it together. I did not believe it was possible for 921 pieces to come out of something that looked so easy, but you got me. What I also found challenging was the clear Lego pieces, which all had to be built to make the base of the bottle. Silly me thought it came in larger blocks. But we had fun and it was well worth the money. My only problem is I have children who will destroy it and I'm unsure about taking it all apart just to glue it together or not."
