A sliding rack for holding your dominoes. At 6in long the rack holds 18 dominoes, but slide out the inner piece and instantly double your holding capacity. Great for building your train on your rack, or for when you're down on your luck. The rack can also slide apart into two pieces for when playing with larger groups. And they store face-to-face to save space. Available as single piece, x2, x4 (here), and x8 packs, with or without a train depot.
