เครื่องปั๊มสวมใส่ DiscreetDuo - แผ่นเสริมกรวยปั๊ม (1 ชิ้นเท่านั้น)

After my original insert got stretched out, this replacement sealed properly again and pumping stopped hurting. It's just one insert, so order two if you need both sides.

After two weeks of daily pumping my output dropped because the original insert had stretched out, and swapping in this replacement brought the suction right back. It clicks into the pump housing exactly like the one that came in the box. Ordering just one insert is handy since I only needed to repla

The fit is noticeably snugger than the worn one I'd been putting off replacing, so the suction finally feels consistent again. It clicks into place without any wrestling, which matters at 3 a.m. Glad I stocked up on these.
