The one at King Arthur does not appear to have beads at the tip of each strand, which IMHO get in the way. I'll put it on my watch list for the next time I order from them, probably next year. (They usually have a $3.14 shipping offer for an order or $31.41 or more around Pi day.)
I'm wondering if I put my too-stiff boar bristle brushes in some boiling water if they'd loosen up. Worst that happens is they come apart and I have to throw them away, but I'm close to doing that anyway.
