All eKEY® Mailers are 6 inches tall. They can vary in length. All have pockets that anchor the optical disk in the mail piece as required by the DMM. All eKEY® Mailers can safely carry either standard sized optical disks or mini disks. eKEY® Mailers are protected by Patent # 6,491,160 and other patents pending.
All eKEY® Mailers lift their optical disks to the top of the mail piece. Mini disks are lifted entirely out of the equipment’s belt path. On a standard sized disk the hub of the disk is lifted out of the belt path. Belt pressure on the hub is what causes breakage during processing.

Because eKEY® Mailers eliminate the belt pressure from the hub of the disk, they are able to significantly reduce breakage of their contents during postal processing. We have had no breakage in our tests of this design. See Postal Processing for clarification.
Another benefit specific to eKEY® envelope mailers is that by lifting the disk to the top of the insert, a swing arm inserter can grasp the bottom of the insert without contacting the fragile disk, automating this part of this process.
