Pure cotton, heavy duty. Same pattern on the reverse side of the duvet cover. The reverse of the pillow case is pure white. It is a two-piece item including one single duvet cover and 1 pillow case. No button /poppers/zipper on the duvet cover. An opening on the bottom for putting your duvet in; a small slit on each side of the top corner for easy positioning. The set is in a very good condition, though a small area on the duvet cover was washed out (see photo) but it can be easily hidden if using the other side. Please note: we are not a pet-free household. Item is washed and clean. :)
