Before, once you requested very high thickness with
shell buttons, we always faced difficulties to make the button
straight. If the buttons were crooked, button holes also would
lose control.
With making the most of skillful labor in our very
well organized factory, now we have achieved quite high standard
of straight high thickness shell buttons.
(Trochus 16L 4mm)
(Each pieces have different shape and thickness.)
Natural(Beige), White and Smoked color are available.
*Smoked color can not be very consistent because of material
characteristic.*
