~ ~ ~ ~ ~ And 14kgf (gold filled)? ~ ~ ~
The gold-filled (Gold Filled), is that of high fever and gold material things the weight of the gold layer is greater than or equal to 1/20 of the total weight in the coated brass that becomes the core of the pressure.
Since the gold layer is thicker than the gold-plated, fear that the gold of the surface come bald is little,
It has been a difficult material to cause a metal allergy.
(Because there are of course individual differences, not necessarily the better of all it does not cause allergy.)
However, after use because there is to be discolored by the conditions of use, etc. wipe off the dirt with a soft cloth, I think that you can use it politely long and receive handle it.
