The modules come on a foam pad to protect the lower leads from bending (pic). They're individually packed in an antistatic bag. Each rail has two connectors, this is useful if you have one of those cheap, long breadboards with discontinuous power rails (pic). I tested one module with a 9V battery and a USB power source, all outputs are working and have the right voltage.

Very useful for breadboards experiments. Found the way to use it on a breadboard with one or two power lines. Perfect Very professional packaging
