This may seem a little out in left field, but I would like to get some opinions on how long a brush might last sitting unused and the reprecussions of using say a 20 year old NOS brush. I have seen some NOS brushes bought and sold here, as well as a plethora of vintage brushes. slcsteve, in particular, seems to have some experience in this area based on what I have seen posted.
My son was born in 2006 and I am considering purchasing a B&B brush to present to him when he is a. old enough to shave and b. old enough to appreciate it. This may be 15, or this may be 24. Alternatively, I may purchase one for myself and hand it down. Just doing some pondering and planning before the order links go live.
