Evolution of Christopher's Lunch Bag

I am writing again about Christopher and this time is his lunch bag as he changed his lunch bag four times in the last three terms.

1st Term: 1 Lunch box with three compartents ( 1 for the small drink bottle) - the clip on the cover snapped

2nd Term: 1Decor Lunch box with a divider at the top for sandwich including a small bottle - the cover broke again

3rd Term: 1 Lunch bag with a lunch box and bottle compartment (includes the bottle). He wanted this so he will carry only 1 bag rather than carrying his lunch box and his bottle

Mid 3rd Term: His lunch box was replaced by tupperware sandwich box and the rest of his foods are in the same lunch bag

4th Term: I hope his current lunch bag and sandwich bag will last this whole term!

I did not realise that his lunch box to lunch bag will evolve that quick.
