The Valkyrie RTA is a single coil post less 25mm RTA that pushes the envelope in RTA performance! The deck brings two 2.5mm x 3.0mm individual post holes for easy coil installation encompassed by a ULTEM insert that reduces the chamber and brings the airflow from the top to the side of the coils! True to all current VC atomizers – the Valkryie does not miss the mark in the flavour department, however it brings ample room to fit a large variety of builds for all your vaping needs
