This is a Michael Kors MIRELLA tote bag. I forgot I bought it, so it's unused. I'm not sure if it came with a shoulder strap. Please purchase if you don't need one. There's a tag inside (image 5), but it's new and stiff, so I can't spread it open. The writing is hard to see because it's dark. It's definitely authentic, but please refrain from purchasing if you're concerned. Purchased directly from a Michael Kors store. Size: 20 x 24.5 x 9 cm No accessories included.
