Interesting ,plenty of Ahearnes in Ireland and I notice the Irish Gaelic Style of writing. Now theres a thought It could be possible for some Manufacturer to Put your Name on these Flasks and Personalize it,if it has not already been done.You could put some Iced Tea in these I suppose Camomile and Honey Green Tea.
Tea? A bike mounted flask and you want to put tea in it? Long Island iced tea, maybe, but I am thinking nice Islay single malt.Tea. Hurmph!
