This is a one-handed opening/closing part for a stethoscope. Stethoscope Attachment - Opens and closes/attaches a stethoscope with one hand. *Note: Stethoscope not included. White part only. Please refer to the video for assembly instructions. Forcefully attach it to a general stethoscope and secure the earpiece with a cable tie. The white part is a pre-made item with the top part shaved off to create space. The shaving is not perfect. (-_-;) I made this myself because the price of Ste◯hoscope Wing was high, and it worked fine, with no issues in hearing.
