Knog, known for its silicone lights. The once hugely popular "FROG" is back, incorporating KNOG's latest technology. Equipped with COB LED, it achieves high brightness despite its ultra-compact size. With 9 different illumination modes, it performs well enough for everyday use in the city, such as commuting to work or school. The placement of LEDs on a curved circuit board enhances visibility from the sides, a feature unique to COB. It has a slim and compact design, weighing only 20g. It won't get in the way visually. The large, easy-to-press one-button makes operation simple, even with gloves on. The stretchable strap allows for easy attachment to various parts of a bicycle or a helmet. The FROG model is rechargeable for the first time. Charge it in 3 hours by plugging in a USB Type-C plug. It can be used for over 50 hours on a single charge. The IP65 waterproof rating ensures safety in rain or when washing your bike.

Therefore, I'm listing it as "like new." To save on shipping costs, I may remove the packaging before sending it, so please be aware of this.
