I went all in the other day and purchased a Simpsons M7 Manchurian in faux ivory. I read lots of great reviews on the M7 Manchurian and didn't want to miss out on the rare opportunity to acquire this alluring treasure. Considering that this was a huge purchase (definetly way way too much for a shaving brush), I am having some buyer's remorse. I was wondering if I should just try to resell it, return it, or keep it. Does anyone know how long this brush could potentially last if used on a regular basis? I am hoping it could last a lifetime (if I decide to keep it). I currently have a Simpson Colonel X2L and just purchased a Simpsons Chubby 2 Best (only used once). I thought I would be fine with these two brushes and maybe a good boar brush, but had a case of SBAD and splurged on the M7. If I decide to keep the M7 do you think that might be a foolish mistake? I need advice. Thanks.
