This package must have sat on the shelf too long or the envelopes were badly manufactured because the 'easyclose' does not stick. Tape is required with each envelope
If privacy is what you're looking for these security tint envelopes fit the bill. Literally. We use them to send out our invoices and checks. They work perfectly and are cheap enough to be economic.
Using these envelopes was the best thing I could've ever changes! I have a travel business and on each motor coach tour I like to collect a tip for the driver and with passing an envelope around to each customer you can only imagine all of the germs that are collected. Well after collecting the tip from everyone I would always lick the envelope to close it. After one day of hearing several of my customers coughing on the motor coach I thought to myself about all of the germs that were on that envelope that I licked to seal! Yuk!!!! No longer do I do that! I just pull the tab off and seal :) No germs anymore. I use them in my office too just because you never know what kind of germs are on those envelopes coming from the factory. Staples always provides me with the them at a great price.
