This 2 finger ring can be worn on your index and middle finger, middle, and 4th finger, or 4th finger and pinky. Both rings are the same size, which works well for comfort purposes because the smaller of the 2 fingers is able to move a little bit so your fingers feel good in the ring. Made in many sizes, Please let me know what size the bigger of the 2 fingers you will be wearing the ring on is in the comments section of the order. Cork is sealed, and can be made with 22k gold sealed on top if you wish. The rectangle setting with the cork on it is 5cm x 1.5cm.
