By-pass Ear Cuff Sterling Silver Geometric Shape One-Stroke-Line series


Shapes born from geometric one-stroke line

The shape of the ear cuff is created with drawing one stroke on a square surface.

Everything is connected by one line.

It's interesting to see things differently depending on the direction

The maze-like lines are likely to collide, but they do not.

You can enjoy the different view from the front to the back and from the top to the bottom in different directions.

Delicate matte finish

The surface is completely matte.

I am conscious of the atmosphere of industrial design.

In industrial design, which has made people's lives more convenient, there is beauty in the pursuit of function.

Gold and Silver

There are two colors, gold and silver.

The silver color is 925 Sterling Silver with platinum-based rhodium coating, and the gold color is 925 silver with K18 coating.

The coating prevents the silver from changing color.

Craftsman's final finish determines the quality 

By carefully finishing and polishing the square edges one by one by hand, a sharp line is created.

Ear cuffs are handcrafted with a lot of ingenuity and skill by craftsmen.

By-Pass is the original design of the MENTOSEN logo.
