Care and maintenance

With minimal care, these inserts stay ready for use. After each pumping session, wash with warm, mild soap and rinse thoroughly. For sterilization, submerge in hot water up to 100°C (212°F) for 5–10 minutes, then air dry completely. Storing in a clean, dry space helps preserve the finish and fit over time.

• Clean after each use with warm, mild soap; rinse thoroughly.
• Avoid harsh cleaners; simple soap keeps silicone soft and safe.
• Air dry completely before next use to prevent moisture-related issues.

Find your perfect fit

Fit is personal. If you experience swelling, rubbing, or squeezing during pumping, you may benefit from a different size. Regularly checking fit and rotating inserts can help you maintain a comfortable pumping rhythm across sessions.

• Available sizes: 15, 17, 19, 21 mm for precise tailoring.
• Measure changes over time to choose the most comfortable option.
