Firefly is a special design! A fairy-tale lamp. Even if a battery is too empty to work in a remote control or toy, it still has a little bit of energy. Enough to gently light a few lights. With a few special parts, Firefly takes the last scraps out of the battery, like an electric bottle picker. By shaking the glass dome up and down, you wake up the fireflies. 4 Small LED lights on flexible moving stalks will then light up nicely warm. Just 4 fireflies in a jar :-) Very special. Looks great in your living room but also very nice in the bedroom. Firefly is a collaboration between Danièle Knirim from Hiervandaan and Gregor van Egdom from Vlak. Dimensions: 10 cm. diameter x 13 cm. high. Delivery time: ships in 1 to 3 working days.
