Purchased at the Men's Building in Tokyo. In excellent condition, used a few times. *Returns not accepted to prevent product substitution.* This is the Boston (panto) shape version of the "Atlas" released in 2021SS. This model features the "EVFT (EYEVAN FLAT TOP) - Titanium Rim," an original rim with a flat top surface of 0.7mm x 2.5mm, made possible by "AD (Advanced) Titanium," a new material boasting the highest strength and excellent spring properties among β-titanium. The bridge features a meticulously crafted half-Manray bridge, and the end pieces incorporate brow-shaped design parts inspired by vintage frames from the 1930s. The temples are made of β-titanium, carefully designed to balance weight and provide a comfortable fit, making this a model packed with attention to detail. The sunglasses model comes with two types of lenses: newly developed original CR39 2-curve photochromic lenses and normal lenses.
