All the ampoules we have tried for direct nasal rinses have a sharp nozzle. The syringe fits perfectly in them, so we use them in this way and they have been very helpful to us.

Let me clarify that I bought them as ampoules for nasal rinses for my little one!

1. The vials are made of hard plastic, which means they are difficult to separate from each other.
2. After removing the cap, the nozzle, although it has a large opening, the plastic is hard and sharp at both ends. In combination with the fact that the vial is generally very hard, it does not allow insertion into the nose and pressure for nasal rinsing.

For the aforementioned use, these specific products do not work!
