This highly simulated rhinoplasty training kit is designed based on the real arm. The two sets of veins distributed on the arm are perfect for puncture training functions such as intravenous injection, injection and blood flow. Durable Reseal Arm: The skin of our IV practice arm automatically reseals after each needle rod, allowing repeated punctures at the same site without venous rupture or leakage. Durable and economical with replaceable container and skin.
