It is far easier to use than things that crush the tip and insert it. It is hygienic because it does not touch the part which enters into the ear even if it is picked with a dirty hand. It will be appreciated if you sell it in 5 pieces 10 pieces etc etc.
With a form type that can be mounted with one hand, the 3 M pusher is superior in sound insulation performance but if it is used for a long time my ear will hurt so I will give it to the express 7 kinds tried but now The place is No. 1 (I think that the individual difference in usage feeling is quite large) In the current product, the through hole is not opened but the hole is opened in the partial end
