Big envelope that holds everything under 12 inches

Awesome envelope. I can put all kinds of stuff in it, lick it to seal AND clasp it.

Great value so long as you tape the top seal

The only difference I have noticed between this and the (much) higher priced brands is that the glue you wet when you seal it does not always hold, but since I usually tape the envelope shut anyway, the glue is not a deal-breaker for me. The envelope itself seems just as sturdy the the other brands.

Need These

I can't run my busy tax practice without a supply of these envelopes. We use them to return documents, tax returns, etc. to our clients. The combination of glue on the flap and the clasp give our clients and added feeling of their materials being safe.

Great for basic tasks

As church secretary I use both 9 x 12 and 10 x 13 envelopes when cleaning out the file cabinets annually. The 9 x 12 size is perfect for thin stacks of documents. Also good for mailing.

Member's Mark Clasp Envelopes

Our office could not do without the Member's Mark Clasp Envelopes. We use these envelopes every day for a select quantity of papers to be mailed out. We appreciate the variety of sizes due to the thickness of the papers being mailed out.

Great quality envelopes

These envelopes are a must for my business they are the perfect size for my 8x10 photo's it keeps them protected until the kids get their photos home to their families and makes it easy to sort because I can write on the outside of the envelopes too

Envelopes

These work fine, but in all actuality I wish Sam's would carry the next size larger! I can cannot knock these as they do work. Maybe they will consider offering one more size larger.

Member's Mark Clasp Envelope 9" x 12" (150 ct.)

I bought this a month ago, and it arrived securely boxed. This envelope size is hard to find so when I found the 150 count (instead of 100 count) from Sams Club, I quickly purchased it. However, these envelopes are a thinner paper weight than the same envelopes sold elsewhere. The 150 count should have been a clue, but shopping online it's hard to know until you receive the merchandise. I will keep the envelopes regardless. Probably would not purchase these envelopes again.
