Urea buttons are very resistant to heat treatment, and therefore they are not burning. They are also completely organic, and they are even a kind of imitation of the horn buttons.

The Urea buttons are very difficult to produce. These are not subsequently painted. With them can only be used laser printing, or using the method of combustion to be acquired beautiful or old-fashioned look of the button.
