I currently buy the polystyrene mug mailers from mdp then wrap them with brown paper and stick a label on.
But the polystyrene mug mailers are £39 +vat for 100
which adds a fair whack to each mug.
The cardboard smashproof mailers I have just had a ball ache with, arriving smashed to bits which defeats the object surely?
but I still use the card mailers if I send 2 or more as they then go into a larger double wall box.
Is there a cheap supplier for the two?
