glass lined flasks?
I've read the information and suggestions posted about flasks. I have followed many of them however I have not had any success finding a flask with a description of the lining.
This was a specific request from my husbands Christmas list.
"A lined flask"
Does anyone know of a particular brand of flask or company that sells flasks that have been lined or treated to prevent strange flavors created from the combo of metal and alcohol?
Perhaps all higher end flasks just come this way?
Any insight is appreciated!
