These are perfect for mailing legal-size documents without having to fold them first. I like to send contracts to clients for them to execute and return and I'll use these and put an extra one inside for the client's use in mailing the documents back to me. You end up with a nice straight flat document perfect for scanning into "the system"... I once thought Kraft was only in the food business but I guess they've gotten wild and crazy and decided to join the business world of envelopes and such. And why not? I'm sure they mail lots of documents so they were probably needing something to fit their needs then decided to share the results with the world. I think that's how it happened with the barbecue sauce and mayonnaise too...
Many uses for this envelope....Mail important documents store important papers decorate for a gift package store your seeds for next years plantings fits in your filing cabinet so you can find it.
I use these for mailing appraisal reports. The one issue is the glue does not do the job. I use tape on the ends. Not every one carry this size envelope so I appreciate your doing so.
