The rug was delivered in a plastic bag. After opening the bag I streamed forth intense chemical odor, which, experience has shown originate from plasticizers. This was probably not quite escape the warehouse and in transit. My cats can better perceive the stench chemo course. I hope that this chemical stench exhales on the balcony. By the way was it so added that pulled the trigger through the humidity of the chemicals a pattern on the advertising board. I can not recommend.
