SterileNoIndividually sealed and sterile until opened. Anything that touches the inside of a vial or your skin should be.

Why you’d want it: A dedicated cold spot, away from the salsa and the curious roommates.
Picking tip: Be honest with yourself about what this is: a thermoelectric box that cools about 15–20 °C below the room, so on a warm day it will not hold 2–8 °C. It is the right buy for privacy and for keeping vials away from children, and the wrong buy as a temperature guarantee — for that, the compressor car fridge in the Travel section runs off a wall plug and actually holds a set temperature. Whichever you choose, put a thermometer in it for a week before you trust it.
