ミニヘアブラシ（鏡付き）

The mirror in the lid is surprisingly clear for something this small, and the whole thing folds flat enough to disappear in my jacket pocket. Used it for two weeks of hostel hopping and the hinge still snaps shut like new.

Tossed this in my daypack for a week of day hikes and the fold-down hinge never once popped open on its own. The little mirror inside the lid is way more useful than I expected for fixing hair after a windy summit.

Weighs almost nothing in my pack, but the metal hinge still feels solid after a week of bouncing around on rocky trails. The mirror flips out smoothly and is actually clear enough to check for scrapes before I head back down.
