Salt. Mason-V

SALT. Mason-V is the midcentury square with inserts — mono-block Japanese titanium chassis with proprietary injection-molded inserts that snap in, custom rim-lock, not a heavy acetate block and not plain Mason. SALT. writes a homage to the American midcentury metal that set the standard for tailored fit: the same classic aesthetic, modern mono-block titanium, a proprietary insert so the color actually performs in the rim, a top-down taper so the lens is supported, not pinched. The balanced feel is the point. We sell it as a 50 mm titanium square with inserts you can actually wear, not a wrap and not the all-metal Mason.

Handcrafted in Japan. Aerospace-grade Japanese titanium chassis, injection-molded inserts, custom rim-lock, Japanese componentry. Designed in California. Frame $580.

Who it’s for. Anyone who wants a midcentury square with real insert color in the rim — titanium chassis, snap-in inserts, not the all-metal Mason. 50 mm eye, 18 mm bridge, 142 mm temples, 34.5 mm depth. Come in and check the 50 on your face. Optical frame; we fill the Rx here.

Shape. Square (optical). Manufacturer tags the shape as square and describes a classic midcentury metal: tapered titanium, mono-block construction, proprietary inserts, custom rim-lock, clean color transitions. This listing is Mason-V (with inserts), not Mason.

Material. Aerospace-grade Japanese titanium chassis, mono-block process so there are fewer stress points. Proprietary injection-molded inserts for fit and performance. Top-down tapered thickness to reduce stress on the lens. Custom rim-lock. Japanese componentry. Titanium for lifetime durability with a featherweight feel.

Origin. Designed in California. 100% made in Japan.
