Nail treatment I bought with my own money

This is a nail treatment I bought with my own money. I purchased it for my nails that frequently split and break. As my nails get thinner, they break easily even when I open a can of beer... It’s really sad getting older... I’m starting to get aches and pains here and there... I’m going to try to keep at it, hoping that if I take consistent care of them, my nails will get better.
