Stiffeners for 12" Record Mailers - 305mm x 305mm - Pack of 50

Stiffeners for 12" LPs made from 150K/B/150T corrugated board to give increased rigidity to record mailers.

These are designed to be used alongside our record mailers which can be found here: https://www.eposgear.com/0700358195785

Although we do not think our mailers require additional stiffeners, some customers like to give extra rigidity to their parcels.

Please note: Record Mailers are sold in multiples of 25s and stiffeners are sold in multiples of 50. It is recommended to use two stiffeners per mailer. These mailers provide additional rigidity to the mailer, and are not designed to cover the entire sleeve of the record.
