That's Mahj SoloMahj practice board - Large

I absolutely love 30A Mahjong Studio! The atmosphere is beautiful, welcoming, and fun for players of all skill levels. The events are well organized, and it’s a wonderful place to learn, practice, and meet great people. I also love my solitaire mahjong board from the studio—I use it every day to practice my game. I highly recommend 30A Mahjong Studio to anyone looking to enjoy and improve their mahjong skills!

The plastic is bent and does not lay flat.
