Sized to fit so correct you can take it out easy to clean but won’t stress out the silicone. Those babies are $30 and I hate replacing them. This one has a bit more to the stem then some of the others so that it has a bit more directional control too, for those that prefer it that way. Made in purple rain which would really match up nice to a few of the LE releases and or a custom top. Ships free and will have a few bonus goodies tossed in.
