In games of Warhammer 40,000: Apocalypse, models in the same unit must remain within ½” of each other at all times. The Apocalypse 25mm Movement Trays can mount up to five miniatures with Citadel 25mm Round Bases, making it much quicker and easier to move them around the battlefield while maintaining their unit coherency.
The movement trays are made of transparent plastic, meaning that they will complement your miniatures regardless of the basing scheme that you've used on them. Each set of bases tessellates so you can put together large units of miniatures. There are nine different designs of movement tray (two of each design are supplied) for added variety.
