Chic and Functional Custom Leather Tote Bag

I would like a custom-made tote bag in either black or brown, made from leather, and sized medium. The bag should feature a chic and timeless design, catering to both functionality and style. Typical dimensions for the medium size should be approximately 14 inches in width, 11 inches in height, and 5 inches in depth, providing ample space for daily essentials.

The tote bag should include the following features:
– Double-stitched seams for improved durability and a sophisticated look.
– Sturdy, comfortable leather handles with a drop length of around 9 inches, ensuring the bag can be easily carried on the shoulder or by hand.
– A zippered top closure to keep contents secure.
– An interior featuring one zippered pocket and two slip pockets for better organization of small items such as keys, phone, and wallet.
– A high-quality lining, preferably in a contrasting color for added elegance and easy visibility of contents.
– Optional: A detachable shoulder strap for added versatility and convenience.

The bag should maintain a structured shape to keep its form even when not fully loaded. The leather should be of premium quality, ensuring that the bag ages beautifully over time. Additionally, please ensure that the bag is crafted using non-toxic materials and eco-friendly processes, reflecting a commitment to sustainability in its production.
