A rigid cardboard stiffener cut to the 12-inch vinyl record format. Postal Packaging’s vinyl record stiffeners slide inside any standard padded mailer or large-letter envelope to prevent the flexing that damages record sleeves and grooves in transit. An inexpensive but effective addition to any record dispatch operation, providing the rigidity that keeps albums arriving in the same condition they left. Essential for record shops, independent labels, and online sellers dispatching 12-inch vinyl.
