Foam exercise mats (Hazeldean/Castlefrank area)

I have 30 interlocking foam exercise mats. Each are 24 inches square and are made of high density foam.

These are not suitable for a children's play area. I have used them to protect projects in my home workshop and to protect floors during home improvements. You can see from the photos they have varying amounts of paint, etc on them.

Not every mat interlocks with every mat. There are perhaps three or four different brands, each with a slightly different interlocking "pattern."
