Why not enjoy this double recycling (as it is made of recycled cardboard to begin with) of a disposable phone stand?
Its pretty simple,
1. Take the sleeve off of your luke warm or gone coffee cup
2. Fold in the sides till they hit the edges of the Dunkin Donuts printing
3. Fold in (airports have no scissors) or cut just above the printing
You might be interested to know that if you wish to keep your phone standing in portrait that you can fit your iPhone or Android charing cable in the small crevice.
*To those who are uber cheapskate, you can always just grab a coffee sleeve by the condiments of most every coffee serving establishment.*
