WARNING: The adhesive on the flap is absolutely PITIFUL! I cannot count how many times these envelopes have come open after fealing them. Not worth the price, since you need to keep a roll of tape nearby every time you want to mail something.

We have always purchased these and they were great. However, they have apparently gone downhill. The seals DO NOT stay closed. So now we have to put scotch tape in EVERY SINGLE ONE before mailing.

This powder sugar is excellent. I have a cookie ministry and give away a lot of cookies. I use this in my cookie icing. It gives the icing a smooth texture, great taste, and beautiful appearance. It works well with a piping bag in creating a swirled icing.

Just finished a box of 500 envelopes of another brand; addressing all of them with my printer. The second I opened this box of Member Mark Envelopes, I immediately noticed they were much thinner. So thin that every one of them crinkles in the printer. I am throwing them in the trash and ordering another brand.

These are not as good as the previous ones Sam's carried. After using several, I had an envelope with a check in it that was left sitting a day or two before I mailed it. When I picked it up it had come completely unsealed! Not great when you are sending checks, etc and it makes me so worried about the things I have already sent! Also, the paper stock is not as heavy as the previous ones. Not as big of a deal to me as the quality of adhesive though. The price point is good, but then again not for security envelopes that don't stay sealed.

Doesn't always stay sealed

Great value and excellent quality

I send several hundreds of letters weekly. Buying my envelopes in huge amounts makes sense.

Finally affordable and I can retire my glue stick

Best envelope ever. Best seal ever. No more licking.
