【Size Suggestion】The size system is set for most people but not everyone. Choose ''Size 2+3'' Mix Pack for Adults, “Size 1+2” for kids and women to try out your fit size. In some cases a smaller size fits better so as to form the airtight seal in the ear. | 【Kind Reminder】 Please do make sure the earplugs create AIRTIGHT SEAL in ear before swimming or shower. If not, please contact seller support for personal size suggestion. Thank you.
