40 for all! These mats have all been stored since pre-pandemic but I hand washed and sterilized them all anyways before putting them online. So they are nice and clean! These are 28 full size interlocking play mats with dinosaurs and alphabet letters. There are also 6 almost complete mats with small things missing on just a couple of them. See picture. These mats are the large size mats so they measure at 12” x 12” each instead of the cheaper ones advertised that are only 6” x 6” each!
