Caps for Eye Drops Containers

My wife has an eye condition and she needs to use eye drops quite a few times a day. But the vial are non resealable type. It was a shame to throw out a vial that was 3/4 full and make pharmaceutical companies even richer than they are.
So made these caps for her and we lived happily there after!
I also made a holder for her vials that you might be interested in:
