Tanga offers the Double-Stack Bento Box
with snaps or handle for $5.99
for shipping. That's a buck under the per-unit price we saw a month ago and the lowest total we've seen for a single unit. (It's a current price low by $5.) Each stack comes with a bottom tray with cover, fork, spoon, utensil clasp lid, and easy-snap lid.
Note: It's not specified what color you'll receive.
