RO-BL
Type-RO Black Archive
Type-RO Black Archive is the more structural expression of TANAKA. Its straighter brow and firmer outer line draw attention toward the cheekbone and give the face a sharper outline. In black, that geometry reads with greater compression, depth, and control.
The frame works by strengthening the upper line of the face and carrying that direction outward through the corners. This creates a more defined relation between eye line, cheekbone, and jawline. The effect is distinct, but still quiet.
Karesansui lines are cut into the surface, then refined by hand to guide light across the rim and bridge. The texture is not printed. It is made. The front is built as a rigid structure, then brought to final shape through hand sanding. Rivets hold the assembly. The temple insert slides in and locks with a micro screw. Spring hinges are set for controlled closure and repeatable alignment over time. Sun lenses are flat-profile polyamide with anti-reflection coating.
Black Archive is the open series of TANAKA. Each piece is accompanied by a TANAKA leather case and a lens wipe.
