Color & Bubble Size May Vary
Rosin color can range from light yellow gold to shades of deep amber depending on the strain, terpenes, and cannabinoid content. Notice the bubble? The bubbles play an important part in how the cartridge functions. The coil inside of the cartridge will absorb the oil in a process known as capillary action, which is the movement of liquid within a void. This action helps carry oil through the wick to the heating element.
