A 4-pack of replacement funnels for the Zookeeper Lionfish Containment Device. One size funnel fits all sizes of Zookeeper that REEF sells (Small, Medium, Large).
The Zookeeper is a PVC-tube based lionfish containment device that allows lionfish hunters to securely stow their catch with minimal handling (sold here). The one-way funnel allows the fish to go in and then be stripped from the spear tip as it is withdrawn. With repeated use the funnels eventually wear down.
