When it comes to keeping vape juice fresh for the long haul, VAPORESSO is leading the way with newly-released advanced product- COSS, designed just for this purpose.
COSS has pioneered the world's first e-liquid capsule design, with a large 7.5ml transparent tank that can detach for easy refilling and cleaning. This improves juice shelf life by limiting air exposure and bacteria compared to traditional e-juice tanks.
But where COSS really shines is its patented vacuum sealed storage system integrated into each device. It uses a specialized vacuum process to compress and seal the e-liquid immediately after filling. This removes oxygen and locks in freshness for drastically extended periods.
The vacuum sealing feature also nearly eliminates potential leakage, unlike traditional e-liquid storage tanks which can seep fluid over time. It’s a revolutionary design that preserves the complex flavor notes and vapor quality of e-liquids better than ever.
COSS vape kits also introduce innovative “automatic oil injection” and “automatic liquid injection” systems for unprecedented quality and consistency with each vape. This precision delivery and vacuum freshness allows you to experience e-juice as it was meant to be - at peak flavor and vapor performance, even months after opening.
By employing industry-leading technology to protect e-liquid’s delicate chemistry, COSS has created vapes that offer a uniquely pure, refined and smooth vaping experience. Their commitment to innovation has earned widespread recognition. COSS was honored with a prized Golden Leaf Award for their exceptional product design and engineering.
