I adjusted the size of all parts for a snug fit to the top of the box and this Insert makes set-up and takedown faster and easier. This organizer also allows for vertical storage without a mess and has individual player boxes. You can use player colors for each if you'd like but I prefer the consistency of using one color. The crates and buildings holders can be put straight on to the board for easy and convenient set-up and takedown of the game. Many thanks to the original designer for this great insert!
