Interlocking foam floor mats

Interlocking foam floor mats. 24x24 in in size. Dark gray and light gray color. 21 full pieces and a bunch of cut pieces. Was used for garage floor gym. Some are kind of grungy and have pressure dents in them from treadmill and other equipment, but otherwise in decent shape. Were used to cover approximately 10 ft by 8 ft area I think we bought them from Walmart a few years ago as in the pictures. $30 takes them all!!
