A little something to help you out if you're like me and can't remember little things you've just done, like whether or not you've just locked your car or signed in at your work shift. It might even remind you to do things you've forgotten.
Put the ring on with the cross facing up and when you complete the task rotate the ring to the ticks! Then when the worry sets in you just have to look down and your ring! Perhaps get a couple in different materials and assign a task to each colour.
(I'm more than happy to introduce other sizes upon request, just shoot me a message)
