These came rolled up tightly and that created a memory. I had to roll each one in reverse and rubber band them in order for them to flatten out. They are very thin. The design is cute though.

The mats were wound tightly around a tube thus wouldn't lay flat. I put a heavy object on them overnight but still tended to curl. I put them in the dryer for 4 minutes and they came out perfectly flat!

Brightly colored. It took awhile for them to lie flat because they were rolled so tightly. I like them. Thanks for attention.
