My child is interested in warships of the world and purchased this in December 2023. They attempted to assemble it, but gave up partway through (at step 3 of 13). The assembled parts were disassembled, and after carefully checking that all parts were present according to the manual, it has been returned to a state close to when it was purchased. I hope to pass it on to someone who enjoys blocks, warships, and puzzles. ※For the opened bags 1-3, the original packaging has been discarded, so the parts are stored in zip-lock bags. ※Three small pieces that were tightly fitted during assembly remain as they are, but this does not affect the assembly. Please check the photos for details. 【Product Description】 ・Military block released in November 2021 ・Made by COBI of the EU, WWII Collection German Aircraft Carrier Graf Zeppelin (1/300 scale) ・Number of pieces: 3136PCS ・Parts are divided into 13 groups and assembled in order according to the included manual. ・Compatible with LEGO and other block brands ・Target age: 12 years and older
