Under the condition of suffering from ears tickle or inflow of water into ears, we tend to clean it with cotton swab. But being unaware of the proper length which the cotton swab should be allowed in the auditory canal when we clean our ears, it is easy for the users to cause deafness. This cotton swab is designed in the light of humans’ auditory canal, while you pinch the middle section and stretch it into the ear canal, your finger will be stuck outside the ear canal by restricting the ingress length of this cotton swab. In this case, this special cotton swab can prevent people from piercing eardrums when cleaning their ears.
