Luxe custom designed mahjong mat measuring 32.5” x 32.5” made from 3mm waterproof neoprene with a smooth polyester top and anti-slip rubber backing. Tiles glide effortlessly on the surface and your table is fully protected. The unique edge-to-edge design includes side stitching for the perfect finish. Easy care! Simply spot clean with an oxi cleaner or Tide stick, or wash on gentle with no fabric softener and no spin. (I lay mats flat to dry on a beach towel and flip it every few hours.)
