堅固凸面透明

The stretch on this surprised me — I could pull it to fit right and it snapped back to its shape no problem. That curve-up design actually stays put against my torso instead of sliding around. Way more comfortable than the flat one I had before.

Didn't expect the curve to actually sit right against my torso like that, but it does. It holds its shape well after being stretched into place.

Stretched it a bit to get the placement right and it snapped back to its original shape perfectly. The convex curve sits nicely up along the torso, way more comfortable than I expected for longer wear.
