"UPD" is a bit ambiguous. It could stand for an update or an update date, like software updates often use "UPD" as an abbreviation. Alternatively, it might refer to a specific product model, like a tamper or applicator model number. I need to verify if "UPD" is part of the product's model or a marketing term.
Another angle: sometimes brands create special editions or collaborations with designers or influencers. "Susann" and "Stefan Söll" might be names of designers or influencers associated with the brand. If that's the case, "UPD" could indicate a collaboration edition or a limited run. femjoy susann stefan soell upd
I should check if there's any official website or database for Femjoy products that lists these names. Also, looking into product reviews or discussions in relevant communities (like feminine care forums or social media groups) might provide insights into what these terms mean in the context of Femjoy's offerings.
