If the size of Jacob Colinn rings does not fit, you can send them to us (paying for return shipping) and we will change them to the right size for you. For changing the size, please contact us by e-mail info@jacobcolinn.com. When sending items for resizing, be sure to include a printed and correctly completed return form inside the package. If you do not have the opportunity to print, write down all the information on a piece of paper according to the return form and put it inside the package.
