18/07/2026Honestly, I just needed something that wouldn’t snap after a month. These feel sturdy without being heavy—wore them on a long haul flight and forgot they were on my face. The black color is neutral enough to go with everything, but the polygonal cut keeps it from looking boring. No weird reflections on video calls either. For the price, I’d say it’s a solid grab if you want one pair that does both work and weekend.

18/07/2026I bought these mostly for the silhouette, and they absolutely deliver. The angles catch light differently depending on the time of day, almost like the frame shifts between matte charcoal and true black. Even the temple tips have this subtle textured grip that feels super considered. Paired them with a silk scarf yesterday and got two compliments before lunch. If you’re outgrowing basic round frames but don’t want anything too loud, this hits the sweet spot.

18/07/2026Been wearing these to the office every day for two weeks, and somehow they still look brand new. The black finish doesn’t pick up fingerprints, which is a small thing I really appreciate when I’m in back-to-back meetings. The polygon shape is sharp but not cartoonish—adds just enough edge to a plain button-down. One tiny nitpick: the nose pads could be a touch softer out of the box, but they settled in after a few days.

21/06/2026Snagged these for my 9-to-5 grind and I'm honestly surprised by how light they are. The real win for me is the matte black finish—it doesn’t catch glare from my monitor or slide down when I’m sweating over a deadline. Polygon shape is sharp but doesn’t scream for attention in a conference room. Nose pads sit flush, no red marks after eight hours.

18/06/2026The sculptural vibe of this frame is even better in person. That deep, inky black feels almost like charcoal—sort of melts into your features instead of just sitting there like a chunky plastic block. I adore how the subtle angular cut catches light differently throughout the day; paired with a cream blazer, it instantly elevates a simple outfit into something deliberately artistic.

10/06/2026Bought these because my last pair snapped clean in half at the bridge. The hinges on this one actually feel reinforced, and the acetate has a bit of flex without being bendy-cheap. Black color is true—no weird blue undertones. Did notice the arms run slightly long on me, but a two-minute adjustment at the optician fixed that. Solid everyday frame for the price, no regrets.
