The 6 3/4 envelopes are very popular for business use. This regular blank envelope is perfectly suited for sending official documents such as invoices and letters. The envelope is made using standard 24 lbs bond paper and has a premium wove finish. This 6 3/4 envelope has a pure white color, which makes it ideally suited for formal correspondence. Its smaller dimensions allow it to be put inside #9 and #10 envelopes and it can thus be used as a return envelope. Fully compatible with standard office printers with envelope feeders, the envelope holds the ink well and resists smudging.
