The best for preschool

The Bentgo Kids Lunch Box comes in a variety of colors and designs, has multiple compartments for different foods, and boasts leak-proof technology.

Bentgo offers bento boxes in different sizes, but one of their most popular boxes is the smaller Bentgo Kids Lunch Box. They also offer the same style in a bright color line and fun prints that preschoolers will love.

The box has four main compartments and one smaller compartment that's perfect for dips and sauces. We also love that the bento tray can be removed from the box itself, and the tray is dishwasher- and microwave-safe. The outer box has rubber edges and a drop-proof design, which is perfect for younger kids.

Unlike many other bento boxes, the compartments in this box are leak-proof, making it much more convenient to pack any food without worrying about it ruining the other foods in the box. This lunch box does not have any built-in temperature control, so you'll need to include an ice pack for food that needs to stay cold.

The Bentgo Kids Lunch Box was featured on Working Mother as one of the best lunch boxes, and it tops the Amazon bestsellers list for lunch boxes. A verified purchaser on Amazon has found it durable and loves the design, saying, "Great portions, never leaks, and super sturdy! It's SO nice to be able to send a lot of different foods and not have to worry about getting a bunch of little containers back."

The biggest complaint people have about this specific model is that it's too small. It's a great size for toddlers and preschoolers, but kids will likely outgrow this lunch box by elementary school, and it might even be too small for preschoolers with voracious appetites.

Pros: Multiple color options, leak- and drop-proof design, dishwasher- and microwave-safe

Cons: Small compartments might be too small for kids with big appetites
