BJ CLASSIC COLLECTION CELLULOID Back to the origin of eyewear manufacturing. BJ is committed to celluloid material to create authentic frames. Celluloid is a strong material that produces a beautiful luster. However, due to its flammability, mass production by machines is not possible, and it is rarely used today. At BJ, skilled artisans breathe life into celluloid frames one by one by hand. Furthermore, we are particular about the metal parts to withstand the strength of this celluloid. The hinges connecting temples and fronts of various thicknesses are used according to their type (7-barrel, 5-barrel, 3-barrel) and fixed with rivets. This is also a technique that is rarely used today, but BJ artisans faithfully reproduce it. P-512 C-2 53□17-143
