This proto board is the PCB you always wish you had but never recognized. Adafruit took the basic layout of a quarter-sized breadboard (basically a "tiny" breadboard plus power rails) and turned that into a beautiful PCB. The top has a white screen print and the same markings you know to make transferring components easier. The bottom has the 5 hole pad design, which matches a classic breadboard, with 4 power bus lines on the sides, and no mask, so you can easily cut traces if needed. They use 1.2mm diameter drill holes so that even parts with large leads fit inside. All holes are plated for strength - this will not come off by reworking. The surface is gold plated - they will not oxidize like bare copper. There are also two mounting holes so you can attach the circuit board to your project box.
They are so practical that they decided to put them in a pack of 3. Once you use a Perma-Proto board, you will never go back.
