A set of four acrylic overlays for the player boards.
The overlay is made of clear acrylic with 1.5 mm thickness and it is very light. The weight of one overlay is only 50 g (0.11 lb).
It is possible to store the overlays together with the original insert but the box lid does not close flush by 5 mm.
The overlays cover the entire player board, including the score track, the main play area, and the floor.
