We’ve been using green lunchbox for two years and got a new yellow one for our youngest child. It is different, shape of thermos is round in and outside (old one was square outside and round inside) which is impractical since it is more difficult to open and plastic cover cracked during first month of usage. Rubber separators have now to be detached every day, before it was attached in a way that if it is not dirty you don’t bother taking it down to wash.
