A unique and high quality fun novelty item. Why not use your wine or glass bottles to great effect with this LED bottle light. It helps to create a romantic and magical atmosphere at your occasions. Perfect for all party events. The light automatically changes colours and loops between these colours, changing at regular intervals of approximately five seconds between each colour. The dimensions are 24mm diameter at the widest point and 62mm long. It comes with minimal packaging for the best postage rates. The box is included flatpacked. Features a super bright LED with a cork top (the cork sits outside the bottle, plastic inside - it doesn't act as a bottle stop or cork, it just sits inside the bottle neck). Rechargeable by USB chargers, laptops, or other devices with USB output. Approximately one hour of charge provides around 2.5-3 hours of light time.
