Quality Park #8-5/8 White Double-Window Security Envelopes with Self Seal Closure - 500 Pack

Quality Park #8 5/8 Double-Window envelopes have layered privacy features to keep checks secure. Reveal-N-Seal envelope flaps are perforated to show evidence of tampering. Security tint with pattern makes our envelopes difficult to read through- even when held to light. Double windows fit QuickBooks or other payroll and accounts payable checks. Patented fold-in-place closure won't seal prematurely. Just raise the bottom flap and press to seal. 24 lb. paper. 3-5/8" x 8-5/8". 500 Per box.
