about 10 years or so here, too. but it's about empty. gonna need more with my recent track record vs knives in the kitchen (went a month slicing a different finger on one hand each week) and a couple bad scrapes so far this winter from falls outside.
Hydrogen peroxide is terrible for cuts, it damages the skin.
Cleaning with soapy water and using a bandage to keep the healing skin moist is the best. If you are worried about an infection, like a cut that got dirt in it then use an antibiotic like polysporin.
