The nifty new TWSBI 580 Navy is a beauty! 

Perhaps could have been called another hue of blue other than “Navy”. It appears to be closer to Royal Blue to my eyes … almost a “L’huere bleue” I’d say (pardon my French). it’s definitely a… nifty blue, made all the niftier with my signature BLS panache (included in price!). For a touch of added flair, $25 gets you an add-on of my  Falcon Flex!   Yowza!
Limited stock for a limited time!
