Fluorescent rings are made of a layer of a mixture of epoxy resin and phosphorus. Fluorescence is basically instantaneous, so as soon as you turn off the light, the ring stops fluorescing. The sun can completely charge the phosphor inside the ring. For this reason, the beneficial function of light should be taken into account when planning to recharge fluorescent materials outdoors. In order for the ring to work properly, it needs to be used in a dark environment. The LED light turns on in the dark. It is very easy and convenient to place on your finger as well as be removed. It is ideal for outdoor activities, parties, night activities, concerts and all kinds of nightlife entertainment. They are made of stainless steel for quality and durability.
