``Tension'' and ``natural curves'' created by hand-stitching

There is a bulge that can only be created by hand sewing, which is not found in machine sewing.

The reason why amba's products look somewhat three-dimensional is because each stitch is hand-sewn.

When sewing by hand, attach two needles to each end of the thread, and sew as you tighten the leather.

This "tightening" action creates a natural roundness and warmth around the seams.

The force can be adjusted in millimeters by using the left and right hands.

There is another important secret in our hand sewing.

The key is to change the tightening strength with which you pull the thread with your right and left hands.

By gently loosening the front side and tightly tightening the back side, the leather that is tightly tightened will shrink slightly, creating beautiful tension on the surface.

⸻

Natural curves and three-dimensionality that cannot be created by machines.

This delicate control of the amount of force gently warps the flat leather as if it has come back to life, creating a natural curve that fits comfortably in your hand.

Rather than adding decoration to make it look three-dimensional, the stitching itself brings out the rich expression of the leather.

This is why we continue to insist on hand-sewing.

⸻

Sturdy enough to be loved for a long time and fun to grow.

The hand-sewn seams not only look beautiful, but also boast outstanding durability that will not come undone even if one part breaks.

Exquisite form and durability created by the care of craftsmen.

I would be happy if you could feel how comfortable it fits in your hand as you use it every day.
