At first i had my doubts about this oddball item. However, now that i bought it and received it, I wish I had found this years ago, instead of killing my fingers and hands trying to rub off these lottery tickets. After a minute or two of using a coin to rub off these tickets in the past, my finger joints would be so sore from osteoarthritis. So much that I decided that I wouldn't be doing scratch-offs anymore. Now that i bought this very simple genius tool, scratching lottery tickets causes no strain at all on the joints, and is much more comfortable than even writing on paper with a pen. Plus, it is so easy to stay in the boxes and scratch only where you need to with ease, whereas with coins it can be a sloppy mess. I can't say enough about it, as I'll be buying another one or two for the family.
