Using patented technology, this “Remember Ring” has a hotspot that makes use of a micro thermopile. A day before the date you’re supposed to commemorate, be it an anniversary or a birthday or some special day — it heats up to 120 degrees in 10 seconds only. But it does that every hour all day. The heat doesn’t hurt though. But you will definitely not forgot the big date because of it.
It’s $760 at Alaska Jewelry
