I bought this medal for my nephew's 1st communion and I was very pleased with the quality.  The medal itself is about the size of a nickel and the chain is sturdy.  The image of St. Christopher is clean and defined.  I only wished there was something on the back of the medal like, "Pray for us."  It was blank except for the sterling silver mark.  I think this is a great gift for anyone interested in wearing a St. Christopher medal.
