I was on the Target homepage for something random recently, and this bag popped up. It’s polyurethane, with a magnetic closure and no structure by itself, as near as I can tell. There are a number of fun colors, and I like that most of the bags have a more muted color on the reverse — the reverse of this happy yellow one is a gray, almost putty color. It’s $36.99 at Target.
