Found these at our local Target store.
Tiffin picnic bentos: available in pinks (below, available online) and blues (not shown, stores only) These are like the Vivo 4 layer bentos on Amazon... I'm not sure how different they are, but they are only $19.99 at Target, compared to Vivo's version (priced at $39.99). I got both the tiffin color sets.
And Sassy baby bento: available in pink and blue. (Also available in Babies R Us, Amazon in varied colors, and elsewhere.) We already had one of the multicolored sets from a year or so ago (bento pictured in an older post). Since I loved that set, I figured I'd go ahead and get a blue and pink set. *grins*
