Turquoise nylon and leather business bag, model 8637/2-DS. The current model is 1772, please refer to this page for the differences: https://www.mens-ex.jp/archives/1128057 The turquoise blue color was only available for a short period through official importers and is rare, and it looks great in sunlight, so it's recommended. It has been used about 5 times, and I believe the leather has no stains other than natural aging. Used less than 5 times and never in the rain. - Color: Turquoise - Material: Nylon and leather - Style: Business bag - Model name: 8637/2-DS - Color name: PERVINCA (L.BLUE) Thank you for viewing.
