The eyewear frame “Sapphire 92” in bog oak-maple-bog oak out of the “evolved collection” represents a fine example of ROLF Spectacles’ natural eyewear handcrafted in Tirol, Austria. The delicate and noble frame is of sheer elegance. The design is subtle and timeless with a highlight on the precision and the loving attention to detail in the finishing process. The unique features include the special lens-glazing system and the patented wooden hinge, both invented by ROLF Spectacles. The “evolved collection” combines finest natural materials, excellent design quality and high-quality processing with real craftsmanship. The frames come with a wooden case, which is also handmade and produced in-house in the Tirol.
