These bags are a nice size and seem durable, especially for larger items. However, they arrived with a very strong odor that was noticeable as soon as I opened the package. I'm hoping the smell fades over time, but it was disappointing and worth mentioning. Overall, the bags are functional, but the odor keeps me from giving a higher rating.

Needed it for a shoe box gift & a couple other small clothing items & they fit perfectly. Loved that it came with some tissue paper as well. Pretty sturdy.
