Shank‑back button sized 9 mm (3/8"). An integrated rear shank lifts the button off the fabric, creating clearance for layered buttonholes so closures sit flat and garments drape cleanly. A polished choice for outerwear, knitwear and structured accessories where a raised profile is desirable. Card includes 5 button(s) for coordinated replacements or a refined focal closure. Choose a finish that complements your fabric for a cohesive result.
