Flesled is a unique LED sticker available in two options: Flesled Classic & Flesled Colour. The Classic contains six white LEDs and the Colour contains four multicolor LEDs. Both options include batteries (type CR1620) that guarantee 15 hours of illumination. Flesled can easily be attached under any 0.7L bottle (or larger) with the powerful 3M sticker. Because the Flesled is only 3mm thick, it is hardly noticeable under any bottle.
