*Digs though his purse but gets fingers slapped by wife.*
So paper might have to do with payment or monies. Could be used for coaster by guys who are single though they never would bother.
Is it fake monies like gas bar coupons or in my wife's case Canadian Tire Money.
I never said it was round just that it is about the size of a grape fruit. The check idea is the closest answer to me. If I told you how close it would be a dead giveaway. I am consumable if you want to eat me. It is not the wisest choice of food and you would get something better to eat by using me.
Here I thought I was giving something easy but it turns out your all thinking too hard it really is a very simple answer. Read the clues again and I bet you will get it. In fact I bet you all have some of this sitting not far from you if your not caring it right now.
That is funny because I could not come up with anything besides money--especially with the PAPER thin! Good Job Alskann!
