This is a genuine Storz & Bickel filling chamber reducer made for the Volcano Classic with Easy Valve. It shrinks the chamber down to about 0.2 grams, or the size of a single Storz & Bickel dosing capsule, so you can use less dry herb per session.

• Fits the Volcano Classic with Easy Valve
• Reduces chamber capacity to roughly 0.2g
• Holds one dosing capsule
• Not compatible with Volcano Hybrid or Solid Valve units

Handy for solo sessions or anyone who wants to dial in a smaller amount per fill.
