At the moment, we offer a single size (regular) that is suitable for most adult noses. However, we're currently working on a smaller size that will be available for purchase shortly. We understand that finding the right fit is essential, which is why we have a flexible refund policy in place. If you feel that the regular size is too large, just let us know, and we'll gladly send you a smaller size to try out! For more info on this jump over to our sizing page.
