This set is nearly complete and includes the instruction manual. All pieces have been checked and counted. What’s included: * 142 out of 143 K’NEX Education Gears Building Set 79318 components * Instruction manual Condition notes: * Set is missing 1 small beige connector piece (there are originally 4 total of this piece type, and this set only includes 3) * No original box included * Otherwise 99% complete and fully functional for building projects The missing piece is a very small connector and does not significantly impact most builds, but I want to be fully transparent.
