Unfortunately, it was difficult to open. She is wrapped in a plastic wrap. They are open at the end, but gets the mat not out because they adhered too tightly against the plastic. So you have to cut it, anyway difficult to exchange. But otherwise it is not.
When cutting the plastic fragmented and has sharp edges. I have drawn me a nice cut. That must really improve the manufacturer. The product itself is great though. Because of packing a star deduction.
