頂部B（金剛）

The hollowed-out sides make it feel feather-light in my pocket, yet it still has that satisfying metal heft when you slide it. I've been fidgeting with it all day at my desk and the reduced weight means it never drags my jeans down.

The hollowed-out design makes it feel featherlight in my pocket, yet it still has that satisfying weight when you flick it. I've been fidgeting with it during meetings all week and the texture is just right for thumb rolls.
