18650 Rubber Battery Holder (4 Pack) $2.99

An 18650 Rubber Battery Holder isn’t necessarily a vape accessory you usually think about buying. But you should if you carry extra batteries with you. That’s because they protect the positive and negative ends of the battery from making contact with any items that may activate them like keys or pocket change. They also protect the batteries from moisture as well. They also have a small ring that allows you to fit the 18650 rubber battery holder to any standard key chain. Such a great deal at $2.99 a 4 pack. Seriously… it’s  a small price to pay to safely carry extra batteries.
