Showing 1 to 3 of 3 (1 Pages)

More than just a sheet of cardboard...

Our 12" record mailer stiffeners are a combination of two flute types brought together to provide great strength at incredibly light weight. Great for your records & great for minimising the cost of shipping your precious vinyl LPs.


These double wall 12" Record Mailer Stiffeners are 3000 Micron / 125KT- BE Flute & provide much greater protection than other stiffeners on the market. Both the MusicMax & our envelope style DEFENDA record stiffeners, strengtheners or pads cope convincingly with the weight of a full sherry bottle giving them ample strength to help prevent valuable vinyl LP's being bent whilst in the post.

The actual sizes of our 12" record mailer stiffeners are:

12" Envelope Style Stiffener Size = 317mm x 317mm appx

12" MusicMax Stiffener Size = 330mm x 330mm appx
