Review: Pack it up - Shipping is expensive so I try to keep my packaging at a low price post and still good quality. These bags are perfect; light weight, sturdy and very well priced. Review: Pretty good - I was selling some of my clothing items and even some singular books. I will say I was surprised at the quality. For my clothing it would be great. And for books for extra security I would double package and it has always arrived well with no complaints from clients. Would recommend and I will say the thickness was good enough to not easily rip. Size was good. The color was whatever the least of my concerns. ## Features - Poly mailers for clothing and non-fragile items.
