Silver JD carrier bag. Inside is a black faux velvet pouch with the work GRAVITY embroidered on it. It contains a two part device made from silicone and is white and a faded red. I was on the northbound dart on Thursday 13/11 existing at Grand Canal Dock at 7.35am and put the bag under my seat. I urgently need this back as I use it to manage the pain from spinal injuries. Please contact me on 087 6272844 Kind regards, Sarahjane.
