The Multi-Use Parka
Apparently, this parka is four-in-one. You can strip the layers, use the built-in mittens (or fingerless gloves), remove the hood, and even change the cut of the jacket itself! This would be great for houseless folks who would need a multi-use jacket. There are a lot of different options for this jacket.
Piano Doorbell
If you have people visiting your home who you trust not to abuse the piano doorbell, then this is the perfect purchase for you. It basically works the same way as a regular doorbell, but with a musical twist. Would you get one?
