Find your most comfortable fit with the MammaBump Flange Insert Fit Pack, designed specifically for the Luna® Wearable Breast Pump.

Made from soft, flexible, high-grade silicone, each insert fits securely inside the Luna® flange to reduce the tunnel size and create a more comfortable, customised fit for smaller nipple sizes.

The pack includes four sizes:

• 15 mm
• 17 mm
• 19 mm
• 21 mm

Having multiple sizes on hand makes it easier to find the fit that feels right for you — particularly as nipple size can differ between breasts or change throughout your pumping journey.

Simply insert your selected size into the Luna® flange before pumping.

Compatible with: Luna® Wearable Breast Pump
Material: Soft, flexible silicone
Sizes included: 15 mm, 17 mm, 19 mm and 21 mm

For the best pumping experience, use our nipple ruler to measure your nipple size and refer to the Luna® sizing guide before selecting your insert.
