Using the SpiderTech Left Shoulder Pre - Cut Kinesiology Tape is a breeze. First, make sure your shoulder area is clean and dry. Then, carefully peel off the backing of the tape and apply it to your left shoulder following the natural contours of your body. Smooth it down gently to ensure it adheres well. When using, avoid stretching the tape too tightly as it might cause discomfort. If you have sensitive skin, it's a good idea to do a small patch test first. For maintenance, keep the tape in a cool, dry place. If it gets dirty, you can gently wipe it with a damp cloth. Don't expose it to extreme heat or moisture as it can affect its stickiness. Remember, this tape is for external use only. If you feel any pain or discomfort while using it, remove the tape immediately and consult a professional.
