Sorry photos are a bit rubbish - the cushion is clear so difficult to photograph with just a trusty iPhone
Bought the wrong part number and opened the packet before checking. Can't send it back now the packed has been opened
Haven't fitted it ( obviously, it is the wrong one), or used it. Have re-sealed the pack.
Cost £69 Selling for £40 plus £4 postage.
Note: this is for a replacement cushion only, not the mask or any fixings.
