Huge lot of retailer Knex 3700+ peices

Product Name: Huge lot of retailer Knex 3700+ peices
Knex in good used condition there is one bag on back on the left that has a slightly cracked bigger vehicle base included and some random pieces those are not included in counted total and neither is the vehicle parts above that and that had been untested so I'm uncertain if it works. The rest have been counted and the number is retailer written on the bag and any damaged unusable ones have been removed from the lot one of the booklets has been taken apart one is all there I'm not sure if all the pieces are there for these . If you have any questions or would like any additional pictures please Lmk. There are around 15ish lbs of Knex :).
