This is a two pack that comes with two syringes. These tips are very soft silicone “hose” that’s about 3 inches long. This is the tip we use to crop feed baby birds that are very small from 3 days old or older. We use this tip because it bypasses the trachea and goes direct into the crop without the dangers of rupturing, damaging or hurting the delicate esophagus of the baby bird. Caution must be taken to ensure you squeeze the formula from the syringe very slowly because the hose is so flexible that it may come undone from the tip of the syringe if too much pressure is added. This tip is very thin therefore formula cannot be paste thick. This syringe tip is to be used with experienced professionals only.
