As you can see, ThermoLab has taken the Thermalright approach with their packaging; a brown box with a company logo. This is not what you want to see on a retail shelf, but if you can pull it off with the success Thermalright has seen, then more power to you.
As stated previously, ThermoLab makes a Micro and Nano model. Both are shipped from the factory in the same box and a mark is made in the box to identify one from the other.
Other than the top and the one side, the rest of the box is plain brown-box cardboard.
