As a result OF my tests, I determined that this silicone sponge is a great tool for practicing injections. It provides a realistic flesh-like texture, making it easier for students to understand proper injection technique. Plus, it`s easy to clean and, with proper care, can last for multiple uses. The only con is that it's a bit pricey compared to traditional sponges, but it's worth the investment for quality practice. Overall, a valuable addition to any injection training program..See full review
