Many years of joy and creativity. We’ve been given several boxes of LEGO and bought some ourselves. Don’t know how much they weigh. City LEGO airport x 3 planes and buildings etc Chima x8 boxes at least. Star Wars 1 Indiana jones. Sets put into bags. Not guaranteeing every piece is there but majority would be and there are two boxes colour sorted extra pieces available for those times when pieces maybe missing. Majority of instruction books available. Water damaged some of them but pages still turn.
