SIRIUS vibrating cushion (CT1 C’bury (Cricket Ground))

Vibrating massage cushion for back pain
Surface washable vinyl cover with a hidden zip on the back
Requires 2 x 1.5v batteries (not included)
In full working order
No on/off button and only one setting - once batteries are inserted, it vibrates when you lean back and apply pressure
Identical to a current eBay listing titled 'Vintage Sirius Cushion'
Whilst labelling it up for a bootfair, the Sharpie pen ink leached through the post-it note and onto the vinyl cover - I have tried to remove it but the Sharpie pen has beaten me......

Collection from CT1 Canterbury - a 5 min walk from New Dover Road junction with St Lawrence Road
