Asvape HITA RBA Tool Kit is designed specifically to the Asvape HITA Pod System. The HITA RBA offers users a custom vaping experience by allowing for various builds to be inserted. The Rebuildable unit excels with salt nic e-liquids but can be used with freebase e-juice. Included in the packaging is a screwdriver, 510 adapter (for checking resistance) and a set of O-rings. Each RBA utilizes a friction fit base which allows for easy installation or removal.
