Product details
M1 flange inserts let parents fine-tune fit without buying an entirely different collection cup. The insert sits inside the flange opening to create a smaller tunnel, which can reduce unwanted areola pull and rubbing when the standard opening is too large. Because fit affects comfort and milk removal, inserts are a low-cost but important accessory for users whose measurement falls between the pump’s default flange sizes.

What parents appreciate
- Accessory feedback generally values getting a closer fit and restoring comfort. Exact size choice should be based on measurement rather than popularity.
