I have a single duvet in reasonable condition. Can't tell what tog it is, but guessing 10.5.
Also a double duvet in marked condition so may just be suitable for animal bedding. It is 10.5 tog.
As shown in photo, the single duvet has a cover which is also available. The pillow in the photo was in an unuseable condition and has been binned. The pillowcase is very faded but matched the duvet cover.
Take some or all.
