How to pass an object from one page to another page

In my first page i have two textbox, like wise i have 12 pages with almost all the controls. I have a class called StoreValues which has getter and setter for storing the values of all the controls from page1 to page 12.

In my first page am creating an instance for StoreValues class and storing two textbox values, in my second page i want that object (which i have created in first page) to store values of other controls.

I dont want to use Session object.

Any other suggestion
