Knuckle can not exceed 9" and bracelet will fit as small as 6" tightly.  Can wear the bracelet looser than 6" up to 9" wrist.
 
The idea of a prayer bracelet is to help you remember to pray for a friend or a family member. You can purchase 2 bracelets for two different people you want to pray for, or select a multi-color one for 2 people.
 
If you have a bigger knuckle, then let me know and I will make one just for you.  Just email me with the size of your knuckle and wrist.
