Jiffy Padded Envelopes

Don't use Jiffy Padded envelopes. (#0 Mailers by Sealed Air 77% Recycled Paper Fibers 62% Post-Consumer)

They're not sealed air. Well, technically they are, but they're not bubble wrap and it's horrible.

They're just stuffed with shredded paper. Heavy, SO MUCH FIBRE EVERYWHERE, disgusting.
