    I like the expandable feature as I sell clothing from home and this envelope holds a items that don’t really need a box but most envelopes are too small. The bubble padding adds a bit of protection from what could be a less than gentle delivery process.My only complaint is that they were shipped a in ridiculously large box that could have held about a 12-pack or more of TP.Very wasteful.
