I’m working on a prototype for a physical product: A pack of magnetized smartphone sized dry-erase whiteboards (each pack would contain 8 whiteboards).
Whiteboards are magnetized, so that they can be stick on bigger whiteboards helping you easily visualize user interface flows.
If the product sells, next step would be introducing tablet and/or desktop sizes.
The pack contains a fine point correctable maker, so that it’s easy to write copy or any interface element on your sketches.
This is the 0.6 mm correctable marker that has given me the best results in my initial tests:

And here you can see some pictures of my initial prototypes: https://www.dropbox.com/sh/5opvxvejbyhopza/AABvLAvnqj2oT58QcmWBaEZ2a?dl=0
What do you think? Could this product help you in your app design workflow?
Thanks a lot for your feedback
