Silicone Bellows for INTROVERT Single Dose Hoppers

Individual silicone bellows for my Single Dose Hoppers can be purchased here.

 

V1.1 

The most current and best version. Has a smooth matte surface that is dust resistant, has accurate shape, and has good wall thickness consistency. Note that some "pieces may come with a very slight oval opening, but will conform nicely when placed into the Niche funnel.

 

Subpar

These pieces will have a pronounced distorted form, and possibly other surface blemishes, but they otherwise are fully functional. Although some of the openings of the bellows may look far from circular, they will conform when placed into the Niche funnel. For optimal air-tightness on the Niche Duo, the non-subpar version is recommended.
