“The River” by Days of Wonder is one of those few games that has a great insert, but the meeples and resources still get relegated to ziplock bags! Here is a great solution to keep those pieces organized!
This organizer by The Shipshape Gamer fits nicely down into the main recessed area of the existing insert. The slide-on lid clicks into place allowing you to store your game vertically without pieces flying everywhere! Precision made and carefully crafted out of attractive and durable draftboard (an engineered wood product).
For an extra $1 you can get the lid in clear acrylic as well! The insert comes disassembled, but putting it together is quick and easy. No glue or special tools required!
