Sfera is another beautiful Optima specialty leather named after the word which translates to sphere in Italian. It is done by splitting the aniline dyed hide to uncover a soft sueded surface. Then the small, undulating 'dotted' pattern is applied with Optima's unique process using heat pressured Paliette paper. The nap of the suede against the small pattern provides a beautiful background for many decors.
