=== About metal hammering technique "Shibori" ===

Unlike the forging of the hot working technique, "Shibori" is a Japanese traditional cold working technique.
Properly heat-treated and especially slow-cooled iron can be worked by hand hammering at ordinary temperatures. Also when making like frying pans by forging, the hammer is beating inside of iron sheets, but in "Shibori", it will be beating outside of them like squeezing.
By beating outside like squeezing without hardness change due to temperature change, the iron sheet can be a tough, lightweight, and uniform thickness.
However, using the "Shibori" technique for iron is very difficult and it needs more than twice the time and effort to use for normal soft copper, brass, and silver. For this reason, ”Iron Shibori” is a very rare technique in the world.

=== Safety ===
The materials of the Real Classic Sierra cup are iron and natural Japanese lacquer only! There is no coating with chemical substances. It's completely safe. By virtue of no anticorrosive paint, burning off the chemical paint before use is also unnecessary.

=== About Care ===
