This is a grey 2 tier lampshade for a pendant light fitting. Unfortunately it does not photograph well so this is the only photo of it, however I can say that there is no white mark on it - that is a light reflection of the photo flash - and the white line through it is from the door frame and not part of the light shade!
It was a present but we have LED fittings all over the house now and have no need of a shade like this.
Please reply via Freegle (as mobile reception is disastrous here) and we can arrange collection at a suitable day/time.
