High quality and great presentation
Color: 2 Pack (M+L)
I got the 2 pack in black. The measurements listed are accurate. I measured my gift before ordering and loved having 2 sizes to choose which made for the better final look. The black is a true black, not light or faded, and the texture and thickness of the material made it look so high quality - way nicer than flimsy drugstore gift bags. Love that the handles are ribbons instead of the cheap stiff paper or rope-like ones. The included tissue paper was a perfect finishing touch and made for an impressive finished look.

Very nice but not wide
Color: Large Black
The quality is nice. The height is great but the width is not great. Good for small clothing like a T-shirt or small gifts.

Exactly what you expect--and that's good if you need a black gift bag!
Color: XLarge Black
This wasn't a fancy or elaborate product, but it provided exactly what I needed: a large, black gift bag with a decent supply of tissue paper! As expected, which was nice!
