Surgical Mask Ring: Adjustable Fit Solution Wearing surgical masks has become a necessity in the wake of the Covid-19 virus outbreak. However, many surgical mask sizes are too large for ladies or children, leading to an uncomfortable fit. This innovative back ring solves that problem by tightening the mask and ensuring a better seal around the face. By reducing strain on the earloops, it provides a more secure and comfortable wear experience. The back ring is designed for easy application, making it simpler than traditional back straps. Its 3mm thickness adds rigidity, guaranteeing a reliable fit every time.
