I recently recived a set of four 'Retroneu' fruit knives. All four are in the original plastic bags, though have been opened. They are also accompanied by the velvet-lined box they were purchased in. 3 knives have one very small weathering marks, (bronze) where the bags were left open, while one is perfect mint. I am intrested in knowing the value of these, and if they are worth keeping/selling. You can reach me at my e-mail, crystalnetra@hotmail.com
