I was down to one clean set before a work trip and these spare inserts saved me from panic-pumping in a hotel bathroom. The flanges fit my existing setup perfectly and feel just as sturdy as the originals, so I don’t worry about them wearing out mid-week.

Finally got a spare set for my travel bag, and the flange insert fits snugly into the wearable cups without any leaks. The silicone feels just as durable as the original pieces, so I’m confident it’ll hold up well over time.
