DIY Ring Contact Sensor Housing

So I have a window in my bathroom next to the shower. There is a good a amount of moisure and steam in the bathroom. I was told the Ring Contact Sensors are not designed to withstand that enviroment. I searched the internet and didn't didn't find a way of making the sensor water resistant that worked very well or was compact. I was looking for a small, compact and water resistant container. I thought maybe a Tic Tak container so I tried it. The contact sensor fits perfectly (see photo). I will place lid down so moisure should not fall into the container.The small part of the sensor is just a magnet so it should be fine to get get a little wet.What do you guys think? Will it work?
