Beautiful bag!
Color: Brown
Exactly as pictured. The color is beautiful and rich. The size is perfect, more spacious inside than it looks.
Quality in stitching is also very nice. Steel zippers which I love.
I use this as a daily bag, looks
Durable and has feet so should help make it last.
Also comes with a dust bag.
Great purchase!

Beautiful Genuine Leather Tote That Will Age Well
Color: Coffee, Color: Coffee
I ordered this SV Retro leather tote in the coffee color, and this is actually my second bag from this brand. I absolutely fell in love with the first smaller purse I tried from them, so I was excited to see how this larger tote version compared.
The leather is the real deal. It has that natural look where you can see the grain and slight variations that tell you it is genuine leather. The bag feels sturdy and well constructed, and the zipper is strong and smooth. It has both a top handle and a removable shoulder strap, which gives you a few ways to carry it.
⚡ Real World Highlights
⚡ Genuine leather with beautiful natural grain
⚡ Large tote size that can hold a 13 inch laptop and more
⚡ Multiple interior pockets including zip and slot pockets
⚡ Strong zipper and sturdy construction
⚡ Top handle plus removable shoulder strap for versatility
⚡ Classic coffee color that works with almost anything
Inside the bag there are plenty of pockets which makes organizing everything really easy. There is a zip pocket, multiple slot pockets, and plenty of room for everyday items like a wallet, phone, notebook, and even a small laptop.
The only reason I am giving this one four stars is that it is not quite as eye catching as the smaller bag I ordered previously. I feel like a wider guitar style strap would have added a little more personality and comfort to the design. I may actually swap one from another bag to see how it looks.
That said, this is still a beautiful, durable leather tote that feels like it will last for many years. With proper care, this is the kind of bag that will age nicely and develop even more character over time.
