This 5 compartment stainless steel bento lunchbox and 2 compartment stainless steel lunchbox both have a removable silicone seal to ensure that the lunchbox is completely leakproof both inside the school lunch bag and in between the internal stainless steel compartments.

These are the ULTIMATE lunch boxes.

Smaller lunchbox: 22cm x 14.5cm x 4.5cm (h)
Sandwich compartment 12 x 12cm
Snack compartment 7 x 12cm
Large lunchbox: 25.5 cm x 18.8 cm x 5 cm

Firstly, being stainless steel means it is completely dishwasher safe and it will last a lot longer than plastic lunch boxes. Stainless steel is also healthier when it comes to being in contact with school or daycare lunches. The silicone seal is food grade and also dishwasher safe. It can be removed and dried separately meaning that mould will not be a problem. But the best thing about the silicone seal is that it makes sure the compartments of the lunchbox are leakproof. This is a huge win. It means you can buy multiple lunch boxes and prep them at the start of the week. The stainless steel lunch boxes will stay fresh in the fridge because they have an air tight leakproof seal.

The 5 compartments inside the bento lunchbox is ideal for picky eaters and children who prefer a grazing style of bento lunchbox. Rrp: $89.95

The 2 compartment bento is great for crunch and sip, munch and crunch or for older school children who have two main breaks at school (we use 2 for our 10yr old but they hold a lot of food)! Rrp: $59.95

Total value $149.90
