How do you package single graded packs for shipping?

In the process of selling some of my PSA graded wax packs and was wondering what type of box/envelope people are using to send a single pack. As always, thanks for any information, Tom

Here are the dimensions:
Priority Mail Small Flat Rate Box (currently $5.35 at retail; or less if you pay for postage online) – PPSFRB - Size: 8 5/8" x 5 3/8" x 1 5/8"
<< <i>Small Flat rate priority box with some bubble wrap would work, correct?

I've never owned or sold any graded packs... but the holders are the same as thick/memorabilia cards.
This is how I ship them... never had a problem.
