I'm one of those people that always brings lunch to work. I first got this habit when I was living -- and working -- in Paris. Going out to eat is super expensive, unless you go to a fast-food joint like McDonald's or KFC... The place where I worked actually had a canteen where I could eat a full meal -- bread&cheese, soap, plate, dessert, fruit -- for 5€. Which is a bargain, for theat amount of food. But there was way too much food. Usually I would get just the plate and the dessert and that would be enough for the whole day. But I realized that i was paying for something I wasn't eating and also most of the times I din't really like the food. And with 4€ I can make a much better meal that the one I was getting, so I just started to pack my lunch with me.
One of the best "accessories" I've gotten is this to-go cutlery set. I've recently bought a new one, and I just wanted to show you.
This brand is super good -- I also had a food-container that was actually stolen from my old-office' fridge, and it was the best I ever had! They are phthalate and BPA free, machine washable and they come in a super convenient travel box.
I don't know if you can see from the picture -- It has a snap on system. It comes with 2 handles where you can attach one of the different heads, so that you can always combine two of the three most used cutlery -- spoon, fork and knife. It also comes with two chopstick attachments which is really cool, in my opinion!
I think that one of these sets are a great investment. It is way more convenient and practical to bring these instead of your kitchen' metal ones. And you always have the three options. It's super compact and completely weightless. These are sold at Continete, they cost 4€ and they last a lifetime. They come in 4 different colors (green,blue,pink,purple) which match the containers. It's a great thing to add to your Back to School wishlist.
