Occasionally, I receive padded mailers through the mail and always keep them to reuse. Most address labels, stamps and return address labels can be removed totally. If not, some brown tape will cover what's left. These recycled mailers can be used again, and you've saved the cost of new ones. It's been several years since I have had to purchase any.

By thoroughly removing the labels on shipping boxes they can be easy reused, saving money and resources. This is a page about removing labels from mailing boxes.
