The CCELL Diama is a 510-thread cartridge designed with a diamond-inspired tank and a postless internal structure to maximize oil visibility and presentation. Its design emphasizes both visual clarity and functional performance, offering a clean and modern cartridge. The Diama is built with CCELL’s 3.0 Bio-Heating ceramic core, engineered to deliver smooth and consistent vapor while supporting efficient oil atomization. Its postless tank removes the traditional center post, allowing for a clearer, panoramic view of the oil and improving overall product presentation. The cartridge is available in 1.0ml and 2.0ml capacities and uses a snap-fit mouthpiece for secure assembly. It's constructed with BPA-free thermoplastic housing and designed with a wide opening for easier filling. Diama blends elegance and engineering, offering crystal clear oil visibility and smooth, reliable performance.
