This is my first experience with arrowroot flour/powder and the first Anthony's product item. 1> Arrived promptly, Very well packaged in Heavy duty lined kraft sack designed to be resealable. I had a problem with getting the "zipper" closure to work but I do with most others too. I pre-planned to transfer to a different container so no big deal. 2> The flour is very fine, clean, and is very like cornstarch in appearance and feel. I've only used this so far in some tempura batter and it worked much like cornstarch. Really can't say much more at this point.
