how small a box is OK?

newbish vendor, just curious if anyone knows if there is a limit on how small a pack can be. i want to send out some samples, could literally fit in matchbox, but i'm thinking a few inches square... still too small? domestic US. does USPS have any limits? i searched USPS.com but didn't find anything...

I hear inserting into a small box is more pleasurable.
