We love Sovrin Extracts and we love their Vape Battery Hard Case Kit! if you are out and about and want to roll with your vape set up this is where its at. The battery (350mAh) is buttonless (air drawn) and works perfectly with the Sovrin cartridges. A nice mobile set up to be sure. The high quality plastic body accommodates most 510 threaded cartridges and includes a standard USB dongle style charger in the clamshell hard case. Filled vape cartridges not included and are sold separately.
