Store your project safe and sound in this nice theyatherproof box with a clear top. Adafruit picked up this box because they like the machinable ABS plastic body and tough clear polycarbonate cover, the built in theyatherproof gasket seal, and the easy-open screws that can be taken apart as many times as you wish without worrying about cracking or stripping.
This box measures 80mm x 110mm x 45mm externally. You can fit a half-size Perma-Proto inside if you clip or sand down a corner a few mm, or an Arduino. It will not fit an Arduino Mega, Beaglebone, Menta or Minty Perma-proto.
