Post-it Upgrade?

I do love the act of scribbling a note. I mean I use my phone for note taking all the time but there really is no substitute for picking up a pen and scrawling a note, or a sketch or a message as you head out the door to a loved one. 

The issue is post-its are not brill for the environment, they curl up and fall away and can only be used once. So a clever company has come up with M Note.

These do work well as they can be wiped clean, stick to most surfaces and come in some rather jolly colours. Will they replace such a familiar favourite? Time will tell!
