The Echo can be used with both CBD and hemp flower, concentrates, and 510 thread oil cartridges. This device is made of strong borosilicate glass parts and incredibly heat-resistant silicone. Insert the Armor Bowl and fill it with dry herb to use as a bong. Leave the Armor Bowl inserted, but pop the glass bowl out to reveal the vape pen adapter. This allows any 510 thread oil cartridge to fit right in, for a super smooth vape experience with the added benefit of water filtration. Swap the Armor Bowl for the 90° thermal quartz banger to enjoy any type of concentrate, just heat the banger with a torch. Pull the very top silicone piece out and connect the titanium nail to the end. This creates the nectar collector, which can be used with the included borosilicate glass dabbing dish. Store the accessories you aren't currently using right in the base. This has slots for the nail, banger, and has a built-in non-stick silicone container for concentrate storage directly under your piece.
