Terrible Envelopes
These envelopes rarely will stay sealed and require a piece of tape to ensure the contents stay in. There is not enough adhesive. I have shipped multiple items and have had several complaints about the envelopes arriving unsealed.

Great for a Mass Mailing
These Self-Sealing envelopes made a 60 person mailing task a breeze. Way better than having to lick adhesives and deal with a metal clasp. I’m sold on them.

Your employee came over and opened a new register to process my purchase. It usually works the other way.

Count them. LITERALLY COUNT THEM!
When you have exactly 100 calendars to stuff into envelopes so you buy the 1 box of a 100 envelopes. Then you realize you are 11 short. Easy math means they cheated you 11% of what you were supposed to get. If it was 2 or 3 I could understand it being a problem in automation and excusable. 11 is feels more like they are assuming most people won't notice and those who do...

Just what I needed
I had 72 card stock coloring pages and a pack of 8 crayons to give to my kindergarteners. This was just the perfect way to “wrap” them and distribute to each of them before the holiday break!

Well Made Envelopes
The envelopes are made with a heavier paper and have a nice construction. I thought the price to be very high.

Easy to stuff
I would recommend if you wanted to save time. Just pull the strip to seal; what's not to like.
