Is it really leather?
Doesn’t seem to be genuine leather but rather PVC

Beautiful brown leather, great quality
Color: Coffee
Very nice quality, as described and great size. Not as heavy as my previous all leather purse. No zipper, has magnetic fastener inside and a flap with twist to lock closure. Adjustable strap. Beautiful color. Would definitely buy again in black as I’m fairly certain with proper care this purse will last for years.

Great medium sized purse
Color: Coffee, Color: Coffee
Such a beautiful purse for a reasonable price! I love everything about this purse. It’s the perfect medium size, it holds its shape without being too stiff. The hardware and straps are high quality. Comes with 2 straps (a crossbody and a shoulder strap) that are adjustable. Lots of room inside with a zipper pocket and a side pocket…I’m not even using the storage to its full potential but it can hold a good amount of items with being just a medium sized purse. I added a scarf from Amazon as a fun detail. Every other purse I’ve looked at is either too small or too big/expensive and this is just perfect.
