A Unique Dab Pen

Load It Your Way

To add to the Terp Pen XL’s magic, similar to a traditional dab you can load it directly onto the coil as you inhale or cold start it by preloading. Both will produce some fantastic vapor. What’s the difference between a traditional or cold start dab? A traditional dab is where you inhale first to heat the coils and then apply concentrate during the hit. The cold start is just as it sounds: Pre-load your concentrate if you’d like, pop the cap on and get to where you are going. When you’re ready for a hit, just inhale. The flavorful terpene-filled vapors will hit you immediately as the Terp Pen XL heats up in an instant.

The temperature settings and your delivery method (cold vs. hot) will determine whether you get a more powerful hit versus a richer flavor profile. For those hybrid folks, you can always find a happy middle ground between the two with this customizable experience. You can also preload the quartz bucket that’s tucked nicely into the cap when you need to be extra discreet or take it on the go. To make matters even easier, all you need to do to change the temperature is tap the body of the concentrate pen three times, and voila!

Big Flavor in a Palm-sized Package

The Terp Pen XL is a portable electronic vape pen that is used for concentrates only. This is an elegant piece of tech with an upgraded ceramic coil design that allows for better airflow and bigger hits.

From the nectar collector method through the classic wax vape pen approach, check out the unique ways you can enjoy concentrates with our How to Use the Terp Pen XL step by step guide to get the most out of your dab pen.

Who is the Terp Pen XL for?

The Terp Pen XL is an all-in-one solution for those who enjoy vaping concentrates on the go and without the fuss of more complicated systems like a dab rig. This vaporizer is just a bit bigger than your average writing pen. It fits in a pocket with relative ease, offering a discrete and portable experience for those who like to micro-dose while moving throughout their day. The icing on the cake is the quartz storage compartment attached to the device. This allows you to keep your concentrate in the pen and take a hit straight from the cap. It doesn’t get much easier than that!

Innovative Exposed Ceramic Coil

Unlike many vape pens on the market that utilize a heating chamber of sorts, the Terp Pen XL features an exposed ceramic coil that can be applied directly to the concentrate. This allows you to place the coil directly onto the concentrate, or place the concentrate on the coil, and then sip it up similar to a honey straw. This concentrate pen offers three different temperature options so that you have the flexibility to find your sweet spot.

Size & Colors

The Terp Pen XL is an elegant and compact device that feels solid in the palm of your hand. Just a little plumper than a regular writing utensil, the vape pen should fit comfortably in your pocket, and no one will be the wiser (if subtlety is your thing). This quick-charging device – only 45 minutes! – is made of stainless steel and features a black or silver exterior.

The Terp Pen XL is as simple as removing the cap, inhaling to activate, and applying the coil to the concentrate. Fast, simple, and effective.


All Boundless Technology, LLC products are backed by a 3-year manufacturer warranty. For the Terp Pen series there is a separate 90-day warranty on the coil & battery.

A Dab Rig That Fits In Your Pocket

No adapters or extra hardware required. The Terp Pen XL’s mouthpiece is pre-tapered to fit on most 14mm water pipes. Using the Terp Pen XL with glass allows for a cleaner, smoother hit, as it adds another level of filtration to the experience.

How does it work?

Simply insert the Terp Pen XL with the mouthpiece end first into your water pipe. From there you can cold or hot start it depending on your preference. It’s that simple!
