Old Priority Padded Mailers

[kpkayle-5]

I have many padded mailers from 5 or so years ago. Can I still use them for priority shipping or do I need to order more?

They are the same size as current mailers.

See if the bar code is different.  If it is, that can cause delays. In that case, I would get a fresh supply.

Go ahead and use them @kpkayle-5 . No problems with the padded flat rates from 5 yrs ago.
