With an entire ocean community inside its chamber, the Coral Reef Ecosystem Bong is fully-functional art. The worked glass reef sits on top of a large circ perc that diffuses your smoke. On this coral reef "tunnel" you can find various sea life including colorful fish, bio-luminescent seaweed and an oyster on top. Inside the oyster you will find a large glass marble acting as a pearl. Unlike most reefs, the Coral Reef Ecosystem Bong is very durable and made of thick glass. This bong comes with a matching 14mm male bowl.
