Our process

From fresh frozen to all-in-one

Single-source resin, extracted and filled in-house without distillate, added terpenes, or fillers.
  1. 01

    Fresh frozen

    Whole plants are frozen promptly after harvest to preserve their aromatic compounds and resin.

  2. 02

    Wash and grade

    Ice water separates the trichome heads before each wash and micron range is evaluated for its tier.

  3. 03

    Press and prepare

    Selected hash is pressed into rosin and carefully prepared for a smooth, strain-specific AIO experience.

  4. 04

    Fill the hardware

    The finished rosin is filled into 0.5mL all-glass all-in-one hardware with nothing added back.

Care & use

Protect the rosin and hardware

A few simple habits help preserve flavor, airflow, and consistency from the first draw to the last.
01

Store upright

Keep the device upright when possible so the rosin stays settled around the intake.

02

Keep it cool

Store at a cool room temperature away from direct sunlight, hot cars, and prolonged heat.

03

Use gentle draws

Take slow, steady draws and allow a short pause between uses to protect flavor and avoid overheating.
