the buttons though [SEP] okay so the buttons are small which creates an issue with pressure and force you need to have a larger button to have larger button holes to use the wider thicker thread yarn in order to secure a mask to keep the force spread out you do this so that you are not tearing off the buttons that save your ears yeah and this does not do that my left side button right side is the phone side is loose after one use the threads stretched still they are thick and cute so you can cut off the buttons and just use them
