This listing is for a Hanna Andersson kid boy / girl new with tags special / limited release short-sleeve "save the seas" sea turtletee from 2010 in a size 110 Euro or size 5. Funny how I complete forgot about it but as soon as I see it I remembered when I putchased it. It was bought for my eldest who is 16! I seriously wonder whether it is some collector's edition.
