Nothing gets closer to the feel of real lymphatics and vessels. The perfect tool for up-and-coming Microsurgeons, CROWNJUN Practice Tubes help simulate the experience of anastomosis with one of the smallest silicone practice tubes on the market—an inner diameter of 0.25 mm! The included high-quality elastomer sheet helps stabilize the tubes during training, and can easily be separated from the tubes by simply applying water. Pair the CROWNJUN Practice Tubes with our Nylon Training Sutures for an unbeatable level of microsurgical training.
