The only place I could see the Maseto was on eBay and it said the owner was going to be gone until April 8th... is there another source? This was just a fast google search....A little late to the game but...
First, I was going to suggest a Maseto brush but @Chan Eil Whiskers beat me to it! I have had two and
really liked them. (I ended up PIFing them to friends who I introduced to wet-shaving). I have a
dozen Rooney Supers and an M&F Finest and I think the Maseto are pretty damn close in terms
of density, softness and backbone. IMHO the best value in badger brushes. The 30mm is a BIG brush.
It will be a bit of a lather hog but you will enjoy it. I really like the Maseto Memphis 26mm two-band,
the handle is great for bowl lathering.
I also bought a Parker faux horn Silvertip as my first brush. I bought it on Amazon because I did not
know any better and it was one of the few brushes available on Amazon Japan (It sure looked pretty!).
It is a floppy brush but none more than some of my Vintage Rooney's. I keep it now for nostalgia's sake.
As far as stands go, as @hairless wonder has pointed
out, prong width is a big issue. I had problems finding a brush holder for my 30mm. What I ended
up doing is taking a cheap plastic one, heating it up gently over a gas stove and then widening the
prongs with a pair of pliers. (I had a black one so it didn't matter if I burned it a little). Or you could
try soaking the plastic one in boiling water to soften the material to widen the prongs. In any case,
enjoy the Maseto!
