In the real world how many Soaps do you really need? People with F.O.M.O., & Collectors seem to be what I call Shave Nurds. Collectors aka in some cases HOARDERS.
There is a U-Tube I watch who drives a Truck for living, and is big time SHA_NERD. Aka Shaving Nerd, he must have no less then 100+ Razors, 125+ Brushes, Soaps over 250+ and if it's made as a MUST HAVE WET SHAVE Accessory, he has every color.
Sickness, or Hobby, only a Mental Health Professional, lr someone like @ SpeedyPC, and make a secure diagnosis. I call it a passion, and he has dumped big buck in his passion.
