PERFECT FOR HEAVY USE OFFICE OR HOME SITUATIONS

This envelope is perfect for heavy use office or home situations. The envelope is a #10, perfect for the 8-1/2”x11” letter. It has a peel-off backing so no more licking the envelope! Remember George Costanza and his fiancé that succumbed to the glue on the envelope? He’d still be engaged had they ordered these envelopes! [Is that a good thing?]A subtle thing I noticed about these envelopes is that they are light weight, more so than similar products. The great thing about that is with rising postage, weight matters. Using these envelopes could make the difference in saving you tens or hundreds of dollars over the long hall, saving on postage by weight.I’m a prolific letter writer and each letter could go to 10 or 20 recipients, so I go through envelopes fast. This will definitely be a reorder item, and you can’t beat the price.

Envelopes

These #10 envelopes are a good item and nice not to lick tab to seal. I use them for bulk mailing and they are good quality. I will buy more as needed.

Quality and performance.

I use the envelopes to send out my tracs and letters to individuals. I am one of Jehovah’s Witnesses and the envelope is perfect for tracs that talk about GODS KINGDOM,WHAT IS IT? Or Will Suffering Ever End? I love them. Just peel and stick.

Quality Envelopes that are Cheaper than Name Brand

First and foremost, I do not get paid to write reviews. I also did not receive this product for free in exchange for a good review.I got these yesterday and I’m definitely pleased with the quality. These seem to be as good as major name brand envelopes for significantly cheaper.These are security envelopes, meaning people will have a hard time reading through them. The self sealing adhesive is very good as well. It’s much better than the name brand that I bought at the local store, where the adhesive isn’t strong enough to keep the envelope closed.I don’t mail all that often, so I figure 500 envelopes will be plenty for a year. I’m hoping the adhesive lasts as long. I will update in the months to comes.
