0.7 mm · 12 g · MagSafeReal aramid (Kevlar-class) weave. Thin, light, warm to the touch — protection that does not announce itself. Made in small batches at the central workshop, not commissioned one at a time.真正的芳綸（凱夫拉級）編織。輕薄、溫潤，是一種不張揚的保護。由中央精品工坊小批量製作，非逐件委託。
Full-grain · Ages with youFull-grain leather over a shock-absorbing frame, cut and stitched to order in a partner atelier. It scuffs, it darkens, and after a year it is yours alone.頭層皮革包覆吸震內框，由合夥人工坊按單裁縫。會刮花、會變深，一年之後它只屬於你。
MIL-STD-810G target · Air cornersEngineering rather than thickness. The plain shell starts at the Entry price; the same structure wrapped in full-grain leather and made to your handset is a Bespoke commission.靠工程，唔係靠厚度。素殼由入門價起；同一套結構包上頭層皮革、按你嘅機型訂造，就屬訂造層。
