The Class M-3 Model B-9 General Utility Non-Theorizing Environmental Control Robot is the most important piece of equipment on the Jupiter-2 mission.

In addition to running air and soil tests on the planets they visit, it also opens all of their bottles! This 4-inch sculpted metal opener has magnets on the back, so it will stay on your refrigerator or lunar module until you're in danger of getting thirsty! Comes packaged in a full-color slipcase.

Retails: $18.
