Use with cotton pads and essential oil. You can slow evaporation by closing the regulator slits and adding water.
e.g.
You just need a toothpick to press the start flaps under the lip around the pin, therefor put the flat lid slider on a hard flat surface and press the cap with that star slits on it. Make sure all flaps are below the lip of the pin - help with a toothpick is necessary.
If you have issues with the snap fit you can use the bayonet twist lock version.
Then just put a cotton pad in the bottom part add 10-20 drops of aroma oil then place the top and bottom in your palms and twist against each other until screw closed.
