Creative 3D Puzzle Paper Model Leaning Tower of Pisa DIY Fun & Educational Toys World Great Architecture Series, 16 Pcs

I was very skeptical prior to purchase. Now, I'd happily purchase any of the 3D Puzzles of this same brand! It it's not paper, it's compressed foam and so very smartly made. All pieces fit together perfectly. Instructions are purely pictorial, so some patience is required, but the end product was WELL worth it! Each piece is incredibly detailed.. and printed on both the outside and inside, even though you can only appreciate the interior detail during assembly. I cannot recommend this product enough!! I know you'll be pleased with it, too!Recommendation: Use glue along the edge of piece #10, then secure with several rubber bands to dry.

Don't really fit into each other. You need the instructions to complete and thus there is nothing to think about.Not worth it

Made of paper, unstable. Kids disappointed.
