So just yesterday, after ordering them Tuesday night from England, received this package of Rosemary & Co. brushes. They came very nicely packed together as seen, and in a cardboard support wrapped by rubber bands. Very nicely arrived, and considering it took from Tuesday to Friday to get from the UK to Omaha, Nebraska I was extremely impressed. Apparently there were no issues getting the brushes through customs. These brushes are their series 33, Kolinsky sable brushes, hopefully in every way just as good as the Winsor & Newtons I've been using now for a few years.
I haven't had a chance to yet actually use them, but as I do, I'll report my impressions sometime in the near future.
