Good quality envelopes.

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.

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 won't be out of envelopes for a while now!!! You don't need name brand envelopes, you need quality envelopes! Member's Mark delivers quality envelopes!!

I was pleased with the quality and performance of these security self sealing envelopes. They are very cost effective at their price point and an excellent product.

I love the large amount of self sealing envelopes which saves trips to buy more! The self seal has great adhesive so there’s no need to tape them shut.

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.

love the press and seal; makes it so fast and easy to send mailings. but, they don't always stay sealed. just a few per box; it's not a huge issue. they run through the printer without issues. always my go-to envelopes.

I couldn't be more pleased with the #10 security envelopes I received for our church use. Paper was of a quality grade and price was too good to be true. As a Plus shopper, shipping was free! Thank you Sam's Club - well done!
