"Poldina Stopper is a battery-powered, portable, and rechargeable lamp with a silicone cap that can be inserted into a bottle, transforming it into a luminous object. A "touch" control on the top of the head allows for switching on, adjusting light intensity, and selecting the light color temperature. With a high protection index, the lamp can also be used outdoors. It has an electronic control system that monitors and signals the remaining battery life, allowing for optimized recharges and always performing them correctly. The silicone cap (food grade) fits various bottle necks and can be easily removed, allowing for convenient lamp recharging on its contact charging base. Charger not included. Poldina Stopper can also be used with the "Lido" ceramic bottles, sold separately."
