Appropriate for everyday business correspondence and home office use, the Monarch envelope (3-7/8” x 7-1/2”) is an attractive solution for your stationery needs. Available in the same size as our 7-3/4 envelope, the Monarch is distinguished by a longer, triangular flap. While the Monarch is a reasonably-priced envelope suitable for frequent usage, the bright-white looking stock looks like you've spent much more on this affordable envelope.
