The Boundless Terp Pen is a portable concentrate vaporizer designed for simplicity and on-the-go use. Its defining feature is a breath-activated operation, eliminating the need for buttons and offering near-instantaneous heating upon inhalation. Constructed from medical-grade stainless steel, this device offers a durable and discreet pen-like form factor. It caters to users who prefer to apply the heating coil directly to their concentrates, providing a straightforward experience. The vapor production is controlled by the length of the draw, giving the user direct influence over their session.

Breath-Activated Operation

The Terp Pen functions without any buttons, relying on a sensor that detects inhalation to activate the heating element. This system provides heat almost instantaneously, allowing for immediate vapor production. The length of the draw directly controls the amount of vapor produced, offering a customizable experience. For safety, the device includes a 10-second automatic shutdown feature to prevent overheating, ensuring a controlled session every time you use it.

Direct Concentrate Application

This device is engineered for direct interaction with cannabis concentrates. Users can apply the coil directly to the concentrate within its container for a seamless experience. Alternatively, a dab tool can be used to pre-load a small amount of material onto the ceramic coil before inhalation. This versatility allows users to adapt their consumption method based on their preference and the type of concentrate being used, whether at home or on the move.

Durable Stainless Steel Body

The Boundless Terp Pen is constructed from medical-grade stainless steel, providing a sturdy and reliable build in a slim, pen-shaped design. It features a magnetic cap for securely covering the coil when not in use. The most recent version is equipped with a 320mAh battery and has been updated with a USB-C charging port for more convenient and modern power management. Its dimensions are 13mm by 134mm, making it easy to store and carry.

Replaceable Ceramic Coils

The heating system of the Terp Pen relies on a replaceable heating element made from ceramic and crushed quartz. This design allows users to easily swap out old coils for new ones, which can help maintain consistent flavor and performance over the lifetime of the device. The coil is engineered to heat concentrates efficiently, directly converting the material into vapor upon contact and inhalation. Two ceramic coils are included with the Terp Pen V2.
