This was designed specifically for the cardboard edition of the game Acquire. The cardboard based tile holders that came with the game were horrible and the holder constantly fell over or the tiles would fall off.
This is designed to hold six tiles with some room to spare. A vertical bar prevents tiles from slipping.
The vertical anti-slip bar also allows the tile holders to stack nicely allowing for a nice flat surface to rest other pieces such as game boards.
