I come in all colors, shapes and sizes,
I'm eays to cary in case of surprises.
I'm pearly and plastic, but mostly of cotton,
There are other alternatives incase I'm forgotten.
You can hold me in your pocket, or even your purse,
I may need to be bigger in case things get worse.
You need at least four of me to last 24 hours,
I may work well, but I don't have super powers.
I'm handy for days that are both heavy and light,
I may work well in the day, but I'm not efficient at nite.
If you use me too long, I can give you quite a shock,
But I'm ALWAYS available and ALWAYS in stock.
