Suggestions for safely shipping small lots of cards?

Just curious how everyone ships small lots (anywhere from 20-50 cards) of fairly inexpensive modern cards (cards will not be individually put in toploaders, maybe team bags?) - I am always careful when shipping, and want to make sure they get where they are going without damage. Thanks for any suggestions!

I like the ones that are nestled inside each other like a normal top/bottom box. They are a little more. You can also get cardboard boxes that will fit around 150 cards. Just use filler to prevent the cards from moving.

I ususally us the 2 piece boxes to ship those type of cards. I put a little piece of foam on the top and elastics around the case and they seem to get their pretty safe all the time
