This is just a small counter tray that you can put inside a 3-ring binder. I play a few Mike Lambo book games, so I wanted something for organizing. I remove the book spine and put the game pages in plastic sleeves for 3-ring binders, so this made sense. The counter tray has nine 14x14x14 mm cells and nine 18x18x14 mm cells and two larger open areas (dice, game markers, ...) which should be enough space for most book style games with counters mounted on chipboard. It was designed to hold 12mm size dice. Most of the time, I just tip the tray over to get everything out, but you can use the counter lifter to raise the counters out as well. This should be enough counter space for most games where the number of counters is not excessive.
