Purchased at a domestic authorized retailer. The chain is removable, and the total length is 71cm, although this is amateur measurement. The lenses have been replaced with gray photochromic lenses (Nikon Viewfit 3 1.60 ECC). The original lenses that came with the purchase are also included. The lens cloth is unopened. The storage bag is unused, but it has wrinkles from the beginning. There are no other accessories besides those in the images. To prevent issues such as product substitution, we cannot accept cancellations or returns after purchase. Thank you for your understanding. #CHANEL
