I bought this little St Christopher to give to a friend to take away with him. I did wonder if it would be too small but I needn't have worried! It is very well made and I am very pleased with it as is my friend. He doesn't wear a lot of jewellery and this little pendant sits discreetly alongside his existing necklace without looking too much. All I will say is if it is to be worn as a single pendant on an adult then this 12mm one is perhaps a little small. But perfect for what I wanted. Delivery was next day and came in a pretty little box. Very happy! Thank you.
