No frills means that something is very basic and doesn't have any extra or fancy parts or features. It's like having a plain peanut butter sandwich without any jelly, honey or other added flavors. No frills items are usually affordable and practical because they focus on what is essential and necessary. For example, a no frills airline might not provide free snacks or drinks on the plane, which helps them keep their ticket prices lower. Overall, no frills products and services are efficient, no-nonsense and designed to keep things simple.
