All stems come complete with our exclusive glow-in-the-dark silicone heat guard to protect your fingers and your glass. They are molded in a hexagon shape to prevent the stems from rolling off your table.
The difference in the Standard Adjustable Stem vs Long Adjustable Stem is simply the length.
The Standard Adjustable Stem is 6″ which is included in the E-Nano kit.
The Long Adjustable Stem is 8″ which can help to allow for more cooling of you vapor.
No matter which stem you choose it will work great with the E-Nano!
