I bought this box of envelopes and just used the first two envelopes this past Friday and planned to mail them on Monday. When I grabbed them to mail them this morning, the seal on both flaps had come open, one partially open and the other completely open. I do not recommend these envelopes for that reason. I called Sam's Club, and they immediately refunded my purchase, so I will buy a different kind now.

Lined & no licking!

Great buy on quality envelopes! Love the peel and stick. Security too!

Members Mark envelopes are good quality. Peel and seal is wonderful. Easy to use and stays tight. No unpeeling ever.

I do a lot of letter writing and these envelopes are great. No mess on sealing the letter. I used the 8x11 computer paper and it fits in these envelope.

Basic letter size envelopes they are a little thin as stated by others they were a really good price and will serve the purpose I am pleased with my purchase.

We go through a lot of envelopes a week and these are a great price and quality product. Only problem is that they are out of stock quite often so we stock up when they're available.

It was very convenient to purchase the envelopes online and picking up curbside. This is one of the best values at Sam's Club. I buy them when I need a few or many.

The quality of this #10 envelope is very good and is one of the better prices out there which is why it is usually hard to find in the stores. Whenever I find them in stock, I usually buy two boxes at a time.

Great price for a great product. They work… they do what they are built to do. The adhesive is strong enough to seal the envelope, without wonton it will open along the way.
