12" Record Mailer Stiffeners - 317mm x 317mm (For Envelope Style & MusicMax QP2 Record Mailers) MM317

MusicMax MM317 Double Wall 12" LP Record Mailer Stiffeners / Strengtheners are a universal Record Mailer Stiffener primarily made for use with Envelope Style Record Mailers.

These high quality LP record mailer stiffeners are designed to fit inside our own & other manufacturers’ envelope style record mailers — providing enhanced protection of the contents for domestic or international postage. They can of course be used in our Classic MusicMax Record Mailer, the MusicMax QP2 or even the MusicMax Twist for those that insist on sending out all of their vinyl shipments with stiffeners. This slightly smaller stiffener can be very useful when you are fighting to keep weight down for your international record mailings.

Constructed in double wall these super record mailer stiffeners are manufactured by us here in the U.K. using the exact same quality board as our original MusicMax MM330 record mailer stiffeners. They are simply a slightly smaller size for use with envelope record mailers.
