Yes, you can bowl if you have nails. However, there are a few things to keep in mind. First, your nails should not be too long. If they are, they may get caught on the ball or interfere with your grip. Second, you'll want to make sure your nails are well-manicured and free of any sharp edges. Otherwise, you could end up scratching the ball or harming yourself. Third, it's important to keep your hands dry when bowling. sweaty palms can make it difficult to hold onto the ball properly.
