OurWorkbench.....The website gave a listing of machines the DBx1 sewing machine needle will fit. The Janome 1600P is one of them. I'll give them a try and if I don't like them I'll offer them up for sale.
As to the round or flat shank...all my machines use a needle that is round on front and flat to the rear. I've noticed needles on Amazon that were flat on both sides, and not listed for use in my machines.
