Envelope Recommendation

[Earl White]

Hello All,

I am preparing to send a large amount of printed letters, and need a good self-sealing envelope recommendation. The envelope size I need is Standard #10 Business Envelope.

I tried Staples and USPS self-sealing envelopes, but the adhesive doesn't close the envelope lid completely and I am forced to put two small pieces of tape on the back-side. Applying the tape takes about 7 seconds per envelope.

7 seconds x 100 envelopes = 11.7 minutes wasted per 100 mailings. Help please!
