Size options and fit

• Four-size combinations and two kit formats (10-piece or 6-piece) provide flexibility for changing needs.
• Selected sizes (13/15/17/19/21mm) offer a snug seal that can support comfortable pumping by aligning with your shield diameter.

Soft-touch comfort and pumping usability

• Soft-touch silicone delivers a gentle feel and a snug fit that may help minimize rubbing or irritation during use.
