Review: Large sized adult lunchbox - Exactly as advertised. This is a large lunchbox for adults or teenagers. It definitely would be too big for a child in school. 4 to 6 cans fit in the top. Plenty of room in the bottom for lunch and snacks. Keeps my food cool till midday without ice packs. It may not hold up for years but at the price I can repurchase. The straps are sturdy and the shoulder strap is removable. It was located in the front small compartment. I almost thought it arrived without it. It was vacuum packed into a tiny package.
Review: extra storage and separation - Really good lunch bag with lots of storage space and useful compartments. I like the durable material and how easy it is to wipe clean. It keeps food fresh for hours and works great for long workdays. My only small complaint is that it’s a little bigger than expected, but overall I’m very happy with it.
