Being able to customize your NookPhone case is pretty cool. And you probably know the drill by now, but if you have the Custom Designs app on your NookPhone, purchase the Custom Design Pro Editor for 800 Miles, and have unlocked the Able Sisters, you will be able to use ID codes for some awesome designs (providing you have a Switch Online membership).
