Description
Product Overview
The LOTBILL Flange Insert Kit is a collection of ten silicone nipple shields ranging from 13 mm to 21 mm in diameter. Designed for compatibility with most wearable breast pumps and standard 24 mm flanges, the inserts are crafted from food‑grade, BPA‑free silicone that provides a soft, skin‑friendly surface. Each piece measures approximately 3.4 × 4.8 × 1.4 inches and weighs 3.53 oz, making the kit lightweight yet durable. The model number FL‑8910 reflects the precision engineering that ensures a snug fit, reducing friction and enhancing milk flow during pumping sessions.

Usage
Mothers can use the inserts at home, in the workplace, or while traveling. Simply select the size that matches the nipple diameter for a comfortable seal, attach it to the pump flange, and begin pumping. The kit is ideal for newborns through toddlers, accommodating changes in nipple size throughout the breastfeeding journey. Because the silicone tolerates high temperatures, the inserts can be sterilized in a steam sterilizer, boiled, or placed in microwave steam bags before each use, ensuring hygiene for both mother and baby.

FAQ
Which breast pump models are compatible?
The inserts work with most wearable pumps and any pump that uses a 24 mm flange, including popular brands like Momcozy S12 Pro, S9 Pro, and similar models. They are not compatible with 27 mm or 28 mm shields.
How do I determine the correct size?
Measure the nipple diameter at its widest point. Start with the size that most closely matches the measurement; the silicone will create a gentle seal. If you feel any squeezing or gaps, try the next size up or down until comfort is achieved.
Can the inserts be reused?
Yes. After each pumping session, wash the insert with mild soap and water, then sterilize using your preferred method. The silicone maintains its shape and elasticity for many uses.
Are the inserts safe for newborns?
Absolutely. The silicone is medical‑grade, BPA‑free, and hypoallergenic, making it safe for both mother and baby during frequent pumping sessions.
