Nursi Luna 3-in-1 Flange Sizing Kit, 10 Silicone Inserts 13–21mm

Why it lives in the nook

This is the kit most of our mothers start with. It was put together with an IBCLC so that the first question — “what size am I?” — gets answered at the kitchen table instead of after weeks of sore sessions. Measure with the ruler, pick the insert one step up, press it into your 24mm shield and pump.

• Five sizes, two of each 13, 15, 17, 19 and 21mm inserts, so each side can wear its own size if they measure differently.
• Made for 24mm shields The inserts sit inside most 24mm electric, wearable and manual pump shields and narrow the tunnel to your size.
• Soft instead of hard Food-grade, BPA-free liquid silicone gives a cushioned edge where hard plastic would rub.
• Ruler, guide and brush in the box Measure before and after a session, check the printed guide, and scrub the tunnels with the sponge brush.
• Dishwasher safe Rinse, run them on the top rack, and swap for a fresh pair roughly every two months.
