Reviews
"A pleasing blue design on the interior is nicely printed and does a good job of providing security and for these reasons I'd choose this brand any time I needed envelopes."
"Great Price. This concerned me when I first opened the package so I sacrificed an envelope to test the seal."
"Great envelopes!"
"We send out fundraising letters in these, so that is not my favorite thing, but the pros outweigh this con, so we keep ordering."
"Hate to admit it, but, the days of licking envelopes are behind me....I've always thought self-sealing envelopes were the epitome of laziness...but, they are really pretty great, not to mention the security feature is nice."
"It takes just as much time to remove the strip covering the adhesive as to moisten the flap."
"Its a shame that amazon is starting to get nothing but junk products anymore."
"These are about half the weight of paper that was in my last batch of envelopes - they're about half as thick a paper."

Reviews
"Completeness (including envelopes, gel pen, stickers, and box). 3. Here's where I think you can corner a niche market: I, like many other. Administrators and professionals, stock up on greeting cards for the. purpose of having them on hand and in stock for office birthdays, sympathy. cards, get well soon, babies, congratulations, etc. I always have to settle for generic crap where half the box gets wasted. because it's inappropriate and useless for my purposes."
"I absolutely love each card in this box!!!"
"Absolutely perfect for what we needed, just a simple variety of greeting cards (it's gets tiresome going to the store for every birthday or other event) and they are very cute."
"The package inside has a ots different design for different purpose use the card that usually you need for entire years.., If you have the package and you don't need buy any card separate, The card design is different than usual outside supermarket design."
"I usually get her blank cards so she can craft what she wants but she specifically asked for pre-printed cards this time around."

"My only SLIGHT beef - and I won't knock off a star because I couldn't find -any- this size that were clear plastic - is that I wish they were 8.5" x 5.5" instead of 7.5" - you know, the size of a folded in half piece of printer paper?"

"I use these for moving / storage box content listing."
"The JNE ones are really good, they are perfect for UPS labels."
"It finally made its way back to me and the plastic sleeve and label were in great condition."

Reviews
"They are in no way worth two dollars and ten cents as far as I can see so you might look at the other offerings in more detail. One last minor note: the company that sells them is apparently called Jam Paper and the listing as Jam Paper Plastic was a bit weird since I wondered for a second what the things were actually made of since a lot of envelopes and file folders are actually paper products, i.e. cardboard."
"Great product for the price."
"as an example, one family member is very ill, so I carry his important medical records with me everywhere, in the bright orange envelope which is easy to find when I need it fast. They're sturdy, yet light weight and well made. The zip closing works well and makes all the contents readily accessible."
"These plastic JAM envelopes were exactly what I wanted them to be: a handy way to contain important papers and items like nametags, etc,."
"These envelopes are perfect for storing folded documents."
"I use these handy envelopes for my lottery cards which I keep in my cars' clove boxes when I go to the lottery retailer."
"Just wish they also came in a non business envelope size that was slightly smaller."
"I was looking for an envelope like bag that my employees could use for at least a year."
