The coil cap is a device designed to prevent thick oil from leaking out. It features a small airflow hole that connects to the mouthpiece, allowing for more concentrated clouds and a thicker flavor. Additionally, it provides a pure taste experience. One of the main advantages of the coil cap is that it saves time on cleaning the entire atomizer. Instead, users can simply wash the coil with alcohol and warm water after vaping. This feature makes maintenance easier and more convenient. The coil cap is a useful accessory for those who enjoy vaping thick oils and want to enhance their vaping experience. By preventing leaks and providing a more concentrated vapor, it allows users to enjoy a more intense flavor. The device is also easy to clean, making it a practical choice for those who value convenience. Overall, the coil cap is a valuable addition to any vaping setup, offering improved performance and ease of use.
