FRIENDLY FARMS COLLABORATION WITH DOJA.PAK Friendly California live resin cartridges are crafted from freshly harvested; flash frozen cannabis flower grown by industry leading cultivators to preserve the essence of the “living” plant. They NEVER filter or use additives in their oil because they believe in the most natural representation of each strain’s unique flavors and effects. That’s the TRU Spectrum™ difference. Connect to any 510 thread battery heated at no more than 3v to enjoy without burning the oil. We invite you to experience why Friendly California is the favorite of cannabis connoisseurs across California. RS11, also known as "RS-11" and "Rainbow Sherbert #11," is made by crossing Pink Guava with OZK. RS11 is more relaxing than energizing.
