Raz Vapes are designed to stay sealed and prevent leaking. They come with advanced leak-resistant technology and high-quality construction to ensure a mess-free vaping experience. The internal structure is built to keep the e-liquid securely contained, even when carried around or stored for extended periods. As long as the device is used and stored properly—upright and away from extreme heat or pressure—it should remain leak-free. However, like any vape, rough handling or damage to the device can potentially cause leaks.
