Made of high-breathable transparent PU material, it is waterproof and bacteria-proof, effectively isolating external contaminants to prevent wound infection. The fully transparent design enables real-time observation of puncture sites without removing the dressing. Featuring mild hypoallergenic adhesive, it fits skin tightly without irritation, no residual glue or pain during removal. Flexible and stretchable, it fits body curves and joint movements, avoiding warping and falling off.
