What are the dimensions of the two individual compartments? I’m trying to determine if a kids bento lunch container (Yumbox) would fit. Thanks.

Thanks for the question! Here are the dimensions for each compartment... Bottom compartment: Approximately 21.5 x 13.5 x 13cm Top compartment: Approximately 21.5 x 13.5 x 8.5cm. However, the top compartment has a dome shape, the depth 13.5cm goes smaller as you move up Hope this helps! Arctic Zone Products

Is the 2-piece leak proof container bpa free?

Thanks for the question! Yes, the food container is BPA free.

Can a replacement for the 2 piece leakproof container (bento box) be ordered?

Sure, could you reach out to us either through the "contact seller" link that should be within your order details or through the customer support contact within the Arctic Zone website? We'll be happy to help you replace the container and just need to get some additional info from you. Thanks! Arctic Zone Products

where does the ice pack go? in the top pocket? and that can also be extended for tall items but then you won't have a place for the ice pack?

This is a great question- There is no dedicated spot (pocket, etc.) that is intended for the ice pack. Instead, it can be packed amongst the contents of the lunch bag. The opening in the top compartment can be used to help pack taller items, can be used to separate items in the lunch bag to help protect items you don’t want to be crushed by others, and also helps to keep certain items away from having direct contact with the ice pack. Thank you again and please let us know if you have any additional questions.
