What is the function of a long kuripe?

Smoother airflow: thanks to its longer channel, the force of the air diminishes before reaching the nose, preventing harsh impact against the nostrils. Intensity control: it allows for a more even and comfortable distribution of the medicinal powder onto the nasal mucosa. Ergonomic comfort: its elongated design facilitates a comfortable arm position and maintains the proper distance between the mouth and nose while blowing. Meditative use: it encourages slower breathing and a more introspective focus during personal practice.
