Perfect for office use. They seal quickly, have no windows, and ensure privacy. The paper is good quality and runs smoothly through the printer. 500 envelopes that deliver exactly what they promise. I’ll definitely buy again.

    • Good envelopes
Size: 500 Count
These envelopes are the classic tri-fold size design that I wanted for mailing mostly folded 8 1/2” x 11” papers. They have peel and press closure for ease of use. The paper quality and texture are good, I trust these envelopes from everything from mailing personal documents even checks. The huge box should last me a long time, no more scrambling for an envelope when I need one. ... show more
