Kraft Envelopes evoke nostalgia and ideas of importance. The Midori Kraft Envelopes are made with the same techniques, but updated with quality and color. Enjoy the updated brown envelope with the same classic button and string closure. Use the envelope to send a letter or to hold special papers and mementos. Eight envelopes come in a package. Each envelope measures 4.5 by 6.7 inches. Envelopes can be put through the mail, but be sure to close them with tape or glue in addition to the string closure. For added safety, inserting the string tie envelope into another envelope will insure its safe arrival.
