You'll have to excuse the quality of this picture but I cropped it way down so you could see the atty. This is a LR306 and the silver material that kind if arched over the top is the wick and the part underneath that gives it its shape is the bridge. The wick helps feed your
juice down into the coil of your atomizer. From what I understand the bridge just helps keep the wicks shape. Some people like to carefully remove the wick and the bridge because doing so offers the cleanest tasting vape from the atomizer. The wick will tend to retain flavors of the different juices if you change juices a lot. If you burn or scorch your
juice while
vaping, the wick will tend to retain that taste as well. Removing both of these things takes a little practice but there's plenty of videos on YouTube describing what to do. Keep in mind that it's not something that you have to do, some people just prefer it.
That's about the easiest way I could describe it, hope it wasn't confusing lol maybe someone can explain better
