I used these to prevent injuries from my child's falls. I am selling them now that I no longer need them. I will wipe each piece on both sides before shipping, but there are many with dents, scratches, and stains. Please only purchase if you understand that these are used items. There are 34 joint mats. There were about 40 edge pieces. - Color: Dark Brown - Size: Approximately 45cm x 45cm, 2cm thick - Shape: Square - Features: Joint type Thank you for looking.
