I believe these are Sand Dollars? I do remember someone telling me they're called something else tho (not in below hashtags) - Can't quite remember. But anyway, the one on the left was given to me by a friend. He found quite a number of these on some island in Thailand but majority were broken, unfortunately. The other one I purchased for about a dollar when I was in Melbourne last year. by virgilskullz http://bit.ly/1EwX1C7
