We did not ship it to you as per your request. Was it like this when you pick it up in person? Did you complain to Kin? It appear there is no crease in the middle on your first picture. Btw, it should not have any ill effect for the sound and heat. We got our shipment in a big box from oversea. All the insulation are protected, straight and never folded. When we get an order, we shipped them out in a big box too. Just let you know, we never have a single complain before.
