[Hampshire] Anyone got any 'SeaShell' drive packing?

Hi,

I have had a couple of drives fail recently and need to RMA them back
to Seagate. They insist [0] that all disks returned are packed first
in those transparent plastic seashell/clamshell things.

Don't suppose anyone has a couple spare, or know where I can get a
couple el-cheapo do they? I seem to have foolishly thrown mine away.

Cheers,
Al.
