Interdepartmental envelopes are designed for sensitive documents. Printed red pattern reads, "personal and confidential," and the larger "Personal and Confidential" messages in blue alert everyone that the envelope is to be opened by the addressee only. Sender signs across the flap once the envelope is sealed. Ideal for expense reports and other sensitive materials. Envelopes are made of sturdy, 28 lb. Gray Kraft stock.
