From my research, I was able to deduce that if used a pea-sized amount (0.01 ounces or 1/16 of a teaspoon) twice a weekday, travel-sized toothpaste would not only last me the week but it would go even further and last 28 days!
Who knew a tiny little thing could last almost a month??
Let me know if any of you guys have had any personal experiences with this. I would be so interested to delve deeper in to this "totally irrelevant yet relevant lifehack" that I have found myself devoting way too much time in.
