This Valve Set includes the new Easy Valve Filling Chamber, new Easy Valve screen set with liquid pad and 5 new Easy Valve Bags. The Easy Valve set is a newly designed valve from Storz & Bickel, the manufacturers of the Volcano Vaporizers. The Easy Valve Set removes the bulky solid valve from being attached to the vapor balloon, leaving only the balloon and mouthpiece - creating a much lighter balloon assembly that will not break if tossed around. This is a genuine Volcano product.
