Willow Sync フランジセット24mm（2個入り）

The 90-day replacement reminder in the listing is spot on—after a month of daily use, these flanges still fit snugly and the edges haven't gotten rough or warped at all. The two-pack is perfect since I can swap one out while the other's washing.

I’ve been using these for a few weeks now and they’re noticeably more comfortable than the ones I had before—the 24mm size fits me perfectly and I don’t feel any pinching. The pack of two is handy since I can rotate them while one dries. Just wish I’d grabbed these sooner.

The 90-day replacement reminder in the listing is spot on—these flanges show wear fast with daily use, so I already grabbed a backup set. Fit is snug and comfortable enough for my morning sessions, and the 24mm seems true to size.
