They put these on sale a lot- I like them... very versatile and works with a number of ages of people.  They are slightly 3D, not very thick.  Very nice quality, comes in a plastic bag inside a velveteen bag inside a navy blue gift box.  works for a 12 year old or a 21 or 31 or even 41 year old.  I got the matching necklace I'm very happy with as well.  A definite would buy again.
