I've had a Brother Label Maker for years, use it for most anything I want to know what's inside the container, etc. So easy to use, the label can be removed to replace with another one too. You can order various colors including metallic rolls of labels, change the size of the printing. Makes life so easy and who can't use easy these days.
When my sister bought her last house, there were so many switches on the walls in her kitchen, it got confusing which switch controlled which light so I made labels so she knew which switch was for which light. Those we didn't want our mother to touch I typed in "DNT" for do not touch as she has a habit of hitting all the switches until she found the correct one she wanted. Now she knows certain ones not to touch and which one she wants actually. So far I haven't done this to my new kitchen/sunroom...............don't ask me why I haven't but just haven't gotten around to it yet. Someday!
