Chinese languages

I have had this necklace for time with some characters on it, and was always curious what they meant. I spent a long time searching for the pinyin name for the characters, but have no idea how to put them together to get some meaning. Please help. The chars. are yi, wan, ben and li and their arrangement is around a box, so I don't know order (counterclockwise, with yi at top).

[%sig%]

i guess it should be yi, ben, wan, and li (simplified characters: 一本万利; traditional characters: 一本萬利).

一 here means one
本 here means (money) capital
万 here means ten thousand, which means very much in quantity
利 here means profit

it's a blessing. wish you can gain ten thousand times of profit out of your capital in an investment.

hope this helps. ^_^
