Gadgeteers aren’t going to be satisfied with a plain brown lunch bag – where’s the fun in that? We want a lunch box that does something special. The Stainless Steel Lunch Jars from Zojirushi should please any gadget lover. They will keep your lunch hot (or cold) for hours, and they look cool doing it. Zojirushi has a variety of styles so you can find the one that fits your needs. The Mr. Bento (shown) and the Bento Classic are both big enough to carry food for more than one meal; the Ms. Bento and the Mini Bento are for smaller appetites or for a single meal. All styles come with either a spork or chopsticks in a protective case; most models also come with carrying bags. The steel lunch jar needs to be preheated with boiling water while you prepare your food, or stored in the freezer overnight if you are packing a cold lunch. We have several of the Zojirushi lunch jars, and I can testify that they keep my husband’s lunch hot from when it’s prepared at 7:30 am until lunch time at 12:00 or 1:00 pm. You can buy the Zojirushi lunch jars at Amazon (search on Zojirushi lunch). Prices range from about $31 to $55, depending on the model.
