Large White Cardboard CD Mailer 6" X 6-3/8" with Adhesive Flap - 50 Pack

Made of glossy-both-sides cardboard. Easy to write on with a ballpoint pen but if you want to use a fountain pen or roller ball with liquid ink, better use a paper label. Also, if you have a rubber stamp with "Media Mail" or "First Class" don't use it because the ink will smear. Use a sticker or write with a ballpoint instead. The cardboard material is thicker than a picture postcard but not quite as thick as the cardboad that comes with a new man's shirt. No internal padding, so the mailer is not as stiff as heavier and considerably more expensive ones I have been buying from Office Depot. However, I have been using Netflix DVD rental service successfully for years and their disk mailers are just flimsy paper, so I conclude that these mailers are very safe for mailing your disks even without the internal padding. The inside is glossy smooth, so it will not damage the surface of your disk. Overall sealed dimensions of the mailer are 6 inches x 5-15/16 inches. Unsealed dimensions are 6 inches x 7-5/8. These mailers are designed to mail disks either bare or in a paper or vinyl sleeve; there is not room inside for a plastic jewel case. The flap is securely self-sealing; just remove a paper strip to expose the adhesive and press the flap closed. The flap incorporates a perforated zip strip for easy opening of the package by the recipient. The description of "50 pack" is a bit misleading. A full pack of these contains more than 50 mailers so I received the quantity of 50 loose; i.e. not in sealed packaging; however that is not problem for me.For calculating postage costs: each mailer weights 0.6 ounces empty, 1.2 ounces with one CD or DVD with paper sleeve, or 1.8 ounces with two disks in paper sleeves. The postal rate structure has gotten more complicated lately... so much so that even the postal clerks can get confused. Your most accurate source to calculate postage is the website: [...]. Within the USA, you can send these mailers first class cheaper than media mail, but there is a surcharge over the letter rate. The mailers are defined as packages instead of letters because they are (1) square, and (2) contain a rigid object (so they have to be hand-canceled). Right now (5/31/2011) the first class letter rate for two ounces is 64 cents, but the first class package rate is 84 cents. Letters sent outside the USA can go first class international. These rates vary by country, but once again there is the surcharge to be paid. For example, first class international letter rate for 2 ounces to Costa Rica is $1.76; package rate is $1.96. For Australia: letter = $1.82; package $2.02. Parenthetically, there is a big stink going on now because the USPS has let Netflix pay the letter rate instead of the package rate for their zillions of DVD mailings.

These are excellent mailers, so 5 stars for that.Just a note warning people not to go to the PO thinking that you'll be able to just talk to the clerk to get the proper 1st class letter rate-- GO PREPARED! PRINT OUT ALL OF YOUR SUPPORTING DOCUMENTS PROVING YOUR POINT AND BRING THEM WITH YOU. To the postal clerk you are just one more uninformed and annoying person that they want to finish with so that you will leave ASAP. They won't think that you have any understanding of postal rates or procedure and will think that you're at best misinformed (but more likely just a pain in the neck).I was unable to discuss the proper rate with the postal clerk unlike one of the previous reviewers. The clerk just wouldn't hear me out to discuss what defined a letter (if it's not more than 6-1/8 inches high by 11-1/2 inches long by 1/4 inch thick and doesn't weigh more than 3.5 ounces, it's considered a letter). He said that since it's made out of stiff cardboard it's a package-- which is NOT one of the criteria for what defines a letter on the USPS website. Unfortunately for me I didn't print anything from the website to show him, but even if I did I think it just would have served to further antagonize him (and I was careful when I asked about the rate to be polite. Alas, he took it as an attack and snapped back). He was getting pretty annoyed-- I had the impression that even if I proved him wrong it wouldn't have been much of a victory so it was worth it for me to just pay the extra $1 and get out of there. I just had to trust his "25 years of experience doing this job, so I know what I'm doing".Am I just venting? Yes-- yes I am. But I also hope this is informative. Good luck!

I am a photographer so I was looking for a CD mailer that is affordable to keep my costs low. These are great. They are not extremely rigid like photo mailers, but are good enough for in-town mailings. I was nervous at first because I typically have used bubble mailers... I just can't imagine the disappointment of my clients getting a broken CD when they are SO! EXCITED! to get their pictures! : ) But, so far so good! No problems! Just write FRAGILE on them to be sure. Oh and writing on them is a bit of an issue by the way - ink does smear. I use a metallic sharpie, and even that rubs off a bit! So, you're really better off with a sticker label.Regarding the postage issue: I was charged $1.95 to mail this. But I used a slim jewel case, not a paper sleeve, so mine was a touch thicker/heavier. I might look into print-at-home postage, because I have to go to the postage office to mail these, as $.45 stamps don't go into $1.95 equally.So maybe this is becoming a problem, these CD mailers are all of a sudden very finicky and require special care. Can't write on them, so now I need to buy labels and design them so they fit into my brand image. Need to buy sleeves instead of jewel cases. Need to look into print at home postage.Hmmm. 4 stars!!
