3 packages were open and are unusable due to the 3 packages being opened. Also 1 other was the wrong item. It’s not a 60 ml piston syringe, but a catheter syringe and can’t use it either. With the problems I can’t leave a positive feedback and I would have to pay to return so neutral feedback is left. I messaged him before I bought and he told me they were factory sealed, but 3 were not sealed and corners exposed so they were contaminated by the air and unusable.
