Product details
These inserts are for the original S9 and S12 wearable cup system and provide smaller flange openings without changing the whole cup. They are most relevant for users who experience rubbing, poor seal or excessive tissue pull with the standard flange. The three smaller sizes make the accessory useful for fitting rather than adding any new pump function.
