To scare you into buying more! ;-)
so you know when it is time to knit or crochet it into a butt-floss style thong?
I was told many medications have an expiration date because the USDA forces companies to do so but most drug potencies will last way beyond those dates.
sir, I want to know one thing that I daily using dental floss since last day ,does it has any expiry date.?<br />
thanking you in anticipation<br />
yours faithfully<br />
